heating
A central heating system provides warmth to the number of spaces within a building and optionally also able to heat domestic hot water from one main source of heat. It is a component of heating, ventilation, and air conditioning (HVAC) systems, which can both cool and warm interior spaces.
I need to extend my central heating from my newly built extension in to the old part of my house. I need to feed 3 rads in separate bedrooms on the first floor and then to feed a towel rail in a bathroom a rad in the utility and a rad in my lounge on the ground floor.
Can I run my 22mm flow &...

Hi, gotta a bit of an issue with refilling my underfloor heating. Am I right in saying that the flow meters along the manifold should be on the top rail, but as you can see they are at the bottom?
Also have I got to loosen off the electrical actuators at the top to refill the system?
Cheers
Hi
I recently did some pipe insulating in my loft.
The only two I didn't do were the vent pipes. Not sure if that is the right term for them? They are the pipes that feed water back into the top of the tanks when there is excess, presumably from steam, expansion, etc. The one going to the cold...

Hello, I have a customer with a modern anthracite vertical radiator and a modern TRV and lockshield.
The radiator makes a loud metallic bang from within the radiator, when it heats up and cools down. I have opened the lockshield fully, lowered the boiler pressure from 2.5 bar to just over 1...

Hello,
We’ve recently moved into a fairly old, fairly big detached house (i.e. fairly draughty, but not too bad by any means) with a fairly new well maintained Worcester combi boiler. We weren’t convinced the heating was working right and then got hit with a £610 energy bill for the first 6...

Hi. I hope some one can help. I have a condensing oil burner and it runs fine but the radiators don't heat. Heats the hot water fine. The pump runs and the thermostat turns the boiler on and off.
