Frequently Asked Questions

What is a combi boiler & how does it work? 
Coldwater is fed into the combi boiler directly from the mains water supply, the gas fuel is then burned to produce heat, which is transferred from the combustion chamber to the water via the heat exchanger.

Your home’s thermostat is able to detect the temperature in your home and when it detects your property's temperature has dropped, it is able to send a signal to the boiler. In response, the boiler will fire up, heat the water and pump it through the system to the radiators.

Once the desired temperature has been achieved, the boiler will reduce its heat output and maintain the status quo, helping to reduce energy waste, while keeping your home warm.

If someone uses a hot tap within the home, or another hot water outlet such as the shower, a component within the boiler called the diverter valve will divert hot water to the taps while they are in use.

Once the tap is turned off, the diverter will be restored to the central heating position. Hot water can be directed to the central heating or the water outlets, but never both simultaneously.

Advantages of combi boilers
If you don’t already have a combi boiler, then you might feel left out and be wondering what all the fuss is about.

But we can reliably inform you that a combi boiler does indeed, live up to the hype.

They provide instant hot water for both your central heating and hot water demands. You might call them a com-bi. It loves both.

But it’s not just having the ease of instant hot water without having to give a giant metal tank one hours’ notice before you want a bath as though Robocop was your butler.

A combi boiler is also remarkably efficient at heating the water – up to 98% efficient.

That makes it superior to immersion heaters.

The efficiency offered by a combi isn’t just a lovely number though, it can make you some outrageous savings on your energy bills – savings you’ll actually notice in monetary value, not like the saving between Asda and Tesco on petrol.

They’re also much kinder to the environment so the birds outside your house choking on Monster Munch packaging have one less thing to worry about.

Combi boilers vs system boilers 
Are you unsure whether you should choose a combi boiler or a system boiler?

The biggest factor in determining whether you will need a combi or a system boiler is your home's hot water demands.

Are multiple bathrooms going to be used at the same time? The system is advised...

If you have a growing family and are likely to be using multiple bathrooms simultaneously, then a system boiler is likely the way to go.

However, for most other circumstances, a combi boiler is advised...


They have a range of power options
Extremely efficient
Easy to repair and maintain
No other components are at risk of failing

Cost of combi boiler installation
The cost of a new central heating boiler is dependent on a variety of different factors, these include the following:

The type of boiler you have installed e.g. combi, regular or system.
The boiler model you choose e.g. mid or premium range.
If you want to relocate your boiler e.g. from the garage to the attic.
If you want to convert your boiler e.g. from combi to regular.
Any add-ons you purchase e.g. magnetic filters, smart controls etc.
Check the latest prices on our combi boilers here.

One of the most common and straightforward types of central heating boiler installations is a straightforward combi swap i.e. replacing your old combi with a new combi. This is much simpler than replacing a combi with a system boiler.

This is due to conversions being more complex to install, taking more time, requiring more labour and more materials. More everything.

The boiler model you choose also has an impact on the cost and at Blackpool Boiler Installations we offer more value-orientated brands such as Ideal and Main , as well as award-winning, premium brands such as Worcester Bosch and Viessmann.
