Frequently Asked Questions (FAQs)

1. What is included in central heating system?

A central heating system has pipework and radiators which are connected to a boiler. The boiler provides the heat and the pump moves heated water from the boiler through the pipework to the radiators, and back to the boiler for reheating. It also provides hot water to the hot taps in your home.

2. What are three types of central heating systems?

There are three main types of central heating boilers – regular, system and combi: Regular boilers are linked to a cold water storage tank in the loft – water is heated by a heat exchanger and pumped to a hot water cylinder ready for you to use.

3. Can you put 2 pumps on a central heating system?

It will as long as both pumps are on the flow or both on the return - you don't want them pumping against each other. If your existing pumps is old - upgrading the pump may work.
