flu flow and spillage test - is this necessary - BG have checked the system today and just want the air vent changed that goes through the outisde wall to provide ventillation to the room that contains the boiler. Thanks for all assistance.

Just had annual BG check for our hot air system. The BG chap said that the rules on ventilation have changed and we need to replace the air vent in the wall (other side of room from the boiler in our utility room). BG have quoted £188 to supply and install (push through the wall!) a vent kit...

Yes - we have got used to hot heads and cold feet. However, Johnson and Starley have this morning advised that this is the correct layout - the return air vents should be above the doors? I have just been trying to work out whether to keep the warm air system or change it for a wet system...

Upstairs we have warm air outlets in the ceiling and return air vents in the wall above the doors. In another post, somebody suggested that this was wrong, and that the return air way should be at the bottom of the door (under the door?, vent in the door?). British Gas look after the system and...

Many thanks for all the info - sounds like BG are the way to go.

Anybody had new heating installed by BG - would you recommend them. We are considering a completely new heating system installed by BG (replace old warm air system with condensing boiler and rads). They seem to have a slightly strange arrangement where they have a QUICK look at the house and...

Thanks simond for your info... Upstairs the air comes out of grills in the ceiling, and the return air vents are in the wall ABOVE the doors - this is wrong? you say they should be at the bottom of the door - so there should be a vent in the actual door? Thanks for your help

Hi, I am not looking for comparison - only wanted some advice on type of wet system to go for. Just need to heat house and water. British Gas have quoted for condensing boiler, new hot water tank and radiators. Local builder says go for pressurised system. I don't know much about it all and am...

Hi and thanks for the advice. We are looking to change away from warm air mainly because of the noise. The return air intake is in our main hall and is noisy as the air is pulled in through the vent. We have a J&S J55-65 Modair boiler with filter which is 10 years old and is still like new. J&S...

I am going to replace the hot air system with a wet system, and would like to ask what type of system people would recommend. The house is a typical 70's style 4 bed detached and British Gas have quoted for a condensing boiler and radiators. I have been told by a local builder that people are...

I really would appreciate any advice on whether we should change our hot air central heating system. We are looking to renovate the house (70's 4 bed detached) and have been told by 3 estate agents and a surveyor that our 'old' hot air system should be changed for a new modern system. The system...
