Hi there ,
I need a bit of advice please . I have been asked to fit three radiators to a bungalow . It has an oil boiler and right next to it is a housing with a big fan that blows air over a radiator . ther is an ordinary circulating pump taking hot water from the boiler thru the rad and back to the boiler . The warm air is blown thru ducts under the floor and into each room . It all worked fine until an extension was built and 2 more bedrooms and an extra bathroom was added , three more warm air outlets were added , but they are not really heating the 3 extra rooms properly .
The customer has asked me if I can fit ordinary water filled rads into each room and I am trying to work out the best way of doing it . There is a 28mm gravity circuit to an ordinary Indirect cylinder and I was hoping to join into that somehow . The 28mm flow rises up from the boiler , up into the loft , along about 3 metres then into a tee that goes up to the F and E tank and down into the airing cupboard into the top of the cylinder coil , out of the bottom . down under the floor and back to the boiler .
I was thinking teeing off the 28mm flow in the loft in 22mm to new pump ( maybe with a bypass valve ) then reducing to 15 mm for the three rads . Running along thru the loft about 20 metres and down to the 3 new rads .
The 15 mm return would then come back and go down into the airing cupboard and connect into the 28mm return pipe low down just before it disapears under the floor back to the boiler . I thought if I used an Injector tee to join into the 28 mm pipe it would hopefully promote the gravity flow thru the cylinder and work okay . We have used Injector tees before and they seem to work o.k.
The pump could be connected to the Programmer so that it worked at the same time as the warm air system .
I hope that I have explained it properly . Do any of you experienced guys think that this will work ? If not can you think of a way that will work please ?
Cheers
