Heat Only Boilers Brands & Prices…

Heat only or conventional boilers typically range in price from approximately £500 to £2000, depending on factors such as brand and model size.

Location: Heat-only boilers are a traditional type commonly found in homes built before 1970 in the UK. These boilers directly provide heating and hot water from a storage cylinder typically located in the airing cupboard. They are fed by a cold water cistern from above, usually in the attic, via gravity. As the expansion cistern is separate, this boiler system requires a reasonable amount of space.

The price of these boilers varies greatly depending on the brand, with models usually starting at around £500 and reaching up to £2000 for certain makes and models.

Heat Only Boiler Brands & Prices…

Please see prices for top brands like;

WORCESTER BOSCH GREENSTAR UTILITY 50 – 70 (OIL) – Typical Price – £1,700 – £1,900

WB GREENSTAR FS 42CDI REGULAR – Typical Price – £1,500-£1700

WORCESTER BOSCH GREENSTAR 30CDI REGULAR – Typical Price -£1,200-£1,300

VAILLANT ECOTEC PLUS 428 – Typical Price – £800 – £900

VAILLANT ECOTEC PLUS 415 – Typical Price – £600-£800

Heat Only Boilers Prices and Sizes

The cost of your heat-only boiler depends on factors like the size of your house and the required fuel type.

Ideal for larger homes, heat-only boilers boast a high flow rate, meeting significant hot water demands, allowing for multiple taps or showers to be used simultaneously. However, they require more space compared to other boilers like combis. Additionally, the use of hot water is constrained by the size of your cylinder, meaning once it’s depleted, you’ll need to wait for it to reheat.

3. And you need to select the right boiler for your budget*

*we can assist you with finance should this be required for your new boiler purchase and installation.

How to pick the right size combi boiler for you property?

• The simplest way to estimate the size of boiler you might need is to count the number of radiators you have.
• If you have Fewer than 10 radiators you require a boiler under 27kW
• With 10-15 radiators you need a boiler between 28kW and 34kW

Best Heat Pumps, Brands & Pricing

There are two different types of heat pumps:

• Ground Source Heat Pumps
• Air Source Heat Pumps

What’s the difference?

Air Source Heat Pumps

The most common type of heat pump is the air source heat pump, which transfers heat between your house and the outside air.

An air source heat pump will extract heat from air outside your property in the same way a fridge extracts heat from its inside.

Work in all temperatures

Air source heat pumps become less efficient the cooler it is outside, but they can be capable of operating sufficiently in temperatures of -15 C, which is 99.99% of the year in the UK.

They have fantastic energy efficiency ratings and although they do have some impact on the environment (as they require electricity to run), they do not combust fuels directly, so in most cases they provide a fantastic way of lowering your carbon footprint.

Ground Source Heat Pumps

A ground source heat pump functions similarly, but it functions by taking the residual warmth from the soil or a water body outside your property and moves it to the inside of the property.

Ground source, water source or geothermal heat pumps achieve higher efficiencies by transferring heat between your house and the ground or nearby water source. Although they are more expensive to install they generally have lower operating costs because they can rely on more constant source temperatures.

Energy Efficiency

The ground source heat pumps also have fantastic energy efficiency ratings and although they do have some impact on the environment (as they require electricity to run), they do not combust fuels directly, so in most cases they too, provide a fantastic way of lowering your carbon footprint.

As per some recent Boiler Guide Articles please find the best heat pumps from each type:

Best air source heat pumps and prices

Please find details of best air source heat pumps as well as an estimate of the costs.

Typically the air source heat pumps or an average property would usually costs between £4,000 – £11,000*.

Comparing air source heat pumps

When trying to choose the best air source heat pump for your home, there are several key features to consider apart from the price.

Types of air source heat pumps

There are two types of air source heat pumps to choose from: air to water or air to air.

• Air to water heat pumps are the most popular as they pride heating and hot water.
• Air to air heat pumps are less popular, as they only provide space heating and not hot water production.

There is also a difference between monobloc or split heat pumps which refers to how the system is set up in your home.

• A monobloc has all of its components (apart from the hot water cylinder in your home) in one compact unit outside the home.
• A split heat pump includes an outdoor with the heat exchanger and refrigerant as well an internal unit inside.

Most homes in the UK are suitable for a monobloc air-to-water heat pump, but a split system may be preferable for more complex installations, as it can be installed up to 30 meters away from the home, offering greater installation flexibility.

Energy Efficiency:

Air source heat pumps boast exceptional efficiency, generating three times as much usable heat for every kilowatt of energy they consume. While some heat pumps may have higher efficiency ratings than others, actual efficiency is influenced by factors like insulation levels, outside temperature, and hot water demand.

Power:

Air source heat pumps come in various outputs to accommodate different home sizes.

It is important to install the right output, but a professional heat pump installer will be able to advise you on this topic.

Is an air source heat pump right for your home?

There are many pros and cons of installing an air source heat pump but if you like the sound of enjoying the ways an air source heat pump could be benefiting your home, such as:

Reduced energy bills

Air source heat pumps are highly efficient heating systems that have the potential to lower your energy bills.

RHI payments

Air to water heat pumps are eligible for quarterly payments over 7 years through the Renewable Heat Incentive scheme.

Better for the environment

Heat pumps use only a small amount of electricity to run and are capable of generating significantly less carbon than fossil fuel heating systems.

Heat your home all year round

Make use of your air source heat pump all year round even in the coldest UK winters.

Easy to maintain

Aside from annual servicing heat pumps a they require very little maintenance and can be left alone to heat your home.

Long lifetime

Many can last for up to 20-25 years. That’s around twice as long as a modern boiler.

However, it is important to note that air source heat pumps are not suitable for every type of home. For an air source heat pump to be effective your home needs to have:

• A high level of insulation
• Outside space for the fan unit
• Large radiators or underfloor heating for maximum heat delivery as heat pumps deliver heat at a lower temperature than boilers
• A small amount of electricity to operate
• A hot water cylinder

To get the best price on an air source heat pump for your home, it is important to compare multiple quotes from different companies.

This can take time but we can help make your research a lot easier.

However, they also manufacture a diverse range of flexoTHERM multi source heat pumps which can be adapted to take heat from the air or water as well as the ground.

These heat pumps are amongst the most quiet during operation and have been awarded Quiet Mark accreditation as a result.

Viessmann ground source heat pumps

Viessmann have an extensive range of ground source heat pumps to choose from with outputs from 5.6 kW all the way up to 96.1 kW.

Their Vitocal range of heat pumps offer a number of benefits for new builds, semi-detached, detached homes and larger residential properties.

If you’re looking for a heat pump that can meet your domestic hot water demands then the Vitocal 222-G has an integral hot water cylinder.

Mitsubishi ground source heat pumps

Mitsubishi Ecodan Monobloc heat pumps can take heat from the ground or a water supply, such as a lake.

These are powerful models with outputs of 45 kW and 60 kW that can be installed as single modules or stacked together to increase the power output (up to 960 kW).

The system delivers water flow temperatures of up to 65°C and is MCS certified which means that it’s eligible for the Renewable Heat Incentive.

Worcester Bosch ground source heat pumps

Worcester Bosch ground source heat pumps are available as either combination (combi) or system models.

All models in the combi range have an integrated hot water cylinder (185 litres) for domestic hot water storage.

Meanwhile, the system range of heat pumps require you to have a separate hot water cylinder* installed.

*It is important to note that this hot water cylinder must be heat pump compatible.

Kensa ground source heat pumps

Kensa offers a comprehensive range of ground source heat pumps, featuring output ratings from 3 kW to 30 kW across three ranges: Evo, Shoebox, and Twin Compact.

All Kensa heat pump ranges boast high efficiency, come with a 5-year warranty, and are eligible for Renewable Heat Incentive (RHI) payments.

The main distinguishing factor among the ranges is price. Shoebox heat pumps are the most budget-friendly, starting from £3,510, while the Twin Compact range commands the highest price tag, starting from £9,230.

Evo heat pumps fall in between, with models in this range starting at £5,862.

A notable advantage of all single-phase Kensa heat pumps is the inclusion of electrical “soft starts,” ensuring minimal energy consumption during startup.

Ground source heat pump installation costs

Ground source heat pumps are not the most budget-friendly heating systems, and their installation process is rather intricate, leading to relatively high installation costs.

The total installation expenses for a ground source heat pump typically range between £10,000 and £18,000. In certain scenarios, these costs can exceed £30,000.

However, it’s essential to consider that while these prices may seem steep, they don’t represent the entire picture. Significant energy bill savings are likely to be achieved, and you may also qualify for Renewable Heat Incentive (RHI) payments, further offsetting the initial investment.

Different Types of Boiler Installations explained too…

There are three main types of boiler installation and each has a different level of complexity which can impact the boiler installation times:

1. Straight Swap
2. Boiler Relocation
3. System Upgrade

Please find more details about each type of installation as well as an estimate of the time each type of installation will take:

Type of installation: Straight swap (same location)!

Details: A straight swap installation, also known as a like-for-like swap, is a type of boiler installation that involves replacing your current system with a boiler of the same type, in the same place.

Time:

This is generally the quickest type of boiler installation as it requires very little change and can often be completed in just one day.

See boiler prices for the costs of your new boiler and boiler installation.

Type of installation: Boiler relocation

Details: A boiler relocation installation requires moving your new boiler to a different location within your property and this could slightly prolong the installation process. Your boiler engineer may have to make changes to the existing pipework or they may have to cap the current pipework and install new elements to the new location.

Time:

This adjustment could add another day on to the standard one day installation making it up to 2 days of installation*.

*It’s worth noting that the further away you choose to install your new boiler, the longer the installation is likely to take which will also have an impact on your price.

See boiler prices for the costs of your new boiler and boiler installation. 

Type of Installation: System Upgrade

Details: System upgrade installations involve homeowners opting to change the type of boiler installed in their property. For instance, transitioning from a heat-only boiler to a combi boiler constitutes a system upgrade. Combi boilers have emerged as the most popular boiler type in the UK, prompting many to upgrade from older heat-only boiler models.

Time:

A system upgrade may extend your installation timeline to up to 3 days* or more, contingent upon the job’s complexity.

*While this duration may seem lengthy, the advantages of transitioning to a more efficient system often justify the investment of time.

Why Choosing the Right Boiler is Important?

Selecting a suitable boiler for your home ensures adequate heating and hot water for your family or property needs. Moreover, opting for a more efficient system could lead to savings on annual energy bills and contribute to reducing your carbon footprint.
