Identifying the problem with your boiler!

If you are having issues with your current boiler, you might be able to repair the boiler or it might need replacing.

If you contact us with your symptoms then we can help you to diagnose the problem and help you determine whether you actually require a new boiler or not, in the first place.

If your boiler is old and outdated or too expensive to repair or cannot be repaired then replacing the boiler may be the best option. But when it comes to new boilers and the replacement process, there’s a lot that you need to know.

Our brief boiler guide about boiler installation will give you all that you need to know, in order to select and purchase the correct boiler for your requirements and/or budget.

The four different types of boilers and heating system installs available!

You can choose from many brands, varieties, and costs of boilers & heating systems for your home, so there’s a lot for you to consider!

The type of boiler or alternative heating system you choose will depend upon your own individual requirements, the requirements of your home and those living within it, how green you want to be, and the amount of money that you want to spend, etc.

The four main boiler options or heating systems that you can choose from are:

1. Heat only boiler / Heat only boiler installation

The heat-only boiler is also known as a regular boiler, a conventional boiler, a traditional model boiler etc. The heat only boiler is standard with older residential properties.

With a regular heat-only boiler, you will have both a hot water cylinder and a separate cold storage tank.

  1. The Common, Heat Only Boiler
  2. A System Boiler
  3. The Combi Boiler
  4. The new Heat Pump!

Advice for older homes

When you have an older home, you might have to continue using this type of boiler, as it is easier and more convenient, with a lot less disruption to the property, to keep your existing installation, so we just replace the boiler.

These conventional Boilers do not perform well with high water pressure, but they are good with the distribution.

This variety allows you to run hot water to once or more than one location for larger properties!

2. A System Boiler / System Boiler Installation

Similar to the traditional type, the system model also requires a hot water cylinder however with the system boiler, you will find that most of the boiler critical components and features are actually part of the system itself.

For this reason, they are often easier to install and require less space for the new boiler installation.

This can be ideal for small properties and new properties etc.

3. Combi Boilers / Combi Boiler Installation

The combi boiler, also known as a combination boiler, is now often the most popular choice for new Boilers, because it combines a central heating boiler with a high-efficiency water heater.

The combination boiler comes in one compact unit.

A combi boiler draws directly from the main lines, so there is no need for a separate storage tank for hot or cold water.

What does a boiler installation cost?

One of the most determining factors, when customers want to purchase and have a new boiler installed, is the cost.

Please take a look at our Boiler Page for a selection of Boilers and their prices. Link!

This budget and amount to pay for a new boiler is a critical part of the decision-making process, and the answer is going to be different for everyone who is looking for a new boiler.

For example, the cost of your boiler installation often depends on the brand of boiler that you choose (see boiler brands page) link!

Worcester Bosch boilers differ from Buderus boilers, and so on so the actual cost of the boiler can impact the cost of your boiler installation. Then the rest of your boiler installation cost is based on the hourly rate of the engineers or the installation team that would be installing your boiler and this can vary widely throughout the country but here at Let’s Heat we try our best to offer highly competitive rates in addition to the high quality and standard of work that we provide in order to offer the best value for money offering that we believe, that we provide. See 4.9 out of 5 Trustpilot scores for assessment of our working standards. link!

The cost for your boiler installation will also be dependant on which of the four varieties of boiler installation or heating systems that you decide to go with.

Also what type of boiler that you have can affect the overall boiler installation cost. Gas boilers are usually the most common type of boilers but there are also oil-based boilers.

Other things that affect buying boilers new include what parts are needed, where you live, unit availability, and so much more.

Here at Let’s Heat, we offer you quality boiler installation at highly competitive prices and we can even provide you with flexible monthly payment options, via our FCA regulated finance options, if you require them.

Comparing boiler replacement solutions and prices:

When it comes to new boilers and boiler replacement services, you should also compare units from the same boiler category.

Take a look at some of the factors that you will need to consider and some additional features and benefits that may come up in your boiler replacement review.

Boiler Replacement – How long should it take?

Boiler replacements can take different amounts of time to complete due to such a varied amount of work that is required for each particular home or business in question, in addition to the type of boiler system selected.

If you have a combi boiler replaced and this is replacing an existing combi boiler, this should take 3-6 hours of installation time.

If you have a system boiler currently and would like to replace that system with a combi boiler, then this would take much longer, usually 1-2 days, due to the fact that this boiler installation requires much more work to convert the system over.

A system boiler replaced with a new system boiler would take about 3-6 hours of installation time.

A heat-only boiler being replaced with a combi boiler or a system boiler would also take approx. 1-2 days of installation time.

Can I get a next-day boiler replacement?

Yes, you can get next-day boiler replacement services with Let’s Heat. If you order your boiler before 12 pm during the colder months, and 2 pm in the warmer months.
