What is a zone valve, and what does it do?

A zone valve is a valve that controls the flow of water to the heating system, not to be confused with a three-port mid-position valve that will also control the hot water cylinder. A zone valve can also be used to separate different heating zones within a heating system, maybe underfloor heating from radiant heating or possibly each floor or even each room could be ‘zoned off’ and controlled independently from one another.
The heating zone valve simply completes an electrical circuit between the external heating controls and the boiler. When the external controls are ‘calling’ for heat, a motor within the zone valve becomes energised and motors across, opening the valve to allow water to flow and simultaneously completing the electrical circuit to energise the heating appliance.

The benefits of a Low Loss Header

A low-loss header is essentially a large box/tube with water that can be fitted inside a boiler. It is a means of hydraulically separating a boiler’s primary circuit from secondary system circuits. As a result, it can improve the boiler’s efficiency and performance while also regulating the flow rate and pressure.
Not only can low-loss headers be used for multiple pumps, but they may also be used to connect various boilers and heat sources to just one system.

Why do you need radiator valves?

They allow you to control how much heat you want your radiator to give out, just like a tap controls the flow of water. Each radiator will have two valves. One will control the amount of hot water that enters the radiator, and the other will balance the system by controlling how much heat comes out of your radiator.
A smart radiator valve can save you money because it allows you to control your house’s temperature room-by-room. If you have a room that gets particularly hot (for example), you can install a smart valve and make it so that that specific radiator comes on less.
