Heating Combi Boiler Installation Guide

 

A combi boiler installation should not be difficult if you have sufficient mains water pressure.

The boiler size and pressure required for your mains water supply will depend on how large your home is.

What size boiler should I use?

The smallest combi boiler available is a 24 kW boiler. This boiler is ideal for small flats or houses with one bathroom. A 30 kW or similar size boiler is the best size for your home if you have two bathrooms. You could get a 28 kW boiler or 32 kW, depending on the model and make of your combi boiler.

A 35 kW combi boiler is the best option if you have more bathrooms than one. This guide is meant to provide you with some information before you hire a heating contractor or get a quote for your heating installation.

Every installation job is unique and each home has its own requirements. A combi boiler installation might not be the best choice if your home is very large.

Which are the best boilers?

This is a hard question to answer, but it was asked often so I will try to answer. Worcester and Vaillant boilers are two of the most trusted and well-known boilers available in the UK.

These are a great option as they can be trusted and reliable. You should expect to pay more for the quality and reliability. It's like buying a BMW or Mercedes car. If you want the best, then you must pay more.

Ideal Heating and Baxi boilers are reliable, but less expensive than Ideal Heating. Ideal Heating is not a well-known brand due to the unreliability of their boiler years ago. However, they now make high quality boilers that are reliable and affordable. I have installed more Ideal Logic+ combi boilers than any other boiler.
