Hi folks
I live in a 4 bed detacted by myself and it's too expensive to heat the whole house (I don't even have hot water on) especially as I'm not on benefits but have a very low income. I have a 28 year old system which is open vented Y plan.
Only the large front rad and the adjoining kitchen/dining rooms rads are on with the doors shut as that's the area of the house I some most of my waking time in.
I appreciate that's not ideal from a boiler efficiency point of view to only be using 2 for all heat output, and I am considering adding 2 radiators - 1 in each of these rooms so each room would have 2 each.
Plumbing wise each of the current 4 downstairs rads drops down from the floor above and backup again. I've located a good place to put the extra rads so that I only need to tee off once from the feed and back to the return as the rads would be on the same wall (albeit opposite sides).
I assume I'll need some kind of bypass though as obviously if one rad is off/TRV restricted I don't want to impact the other one. I'm not sure how to do this - do I just connect the 2nd new rads feed to just before the 1st rads feed and the return to just after the return of the other one?
Also, do I need any special values from the F and R pipes above or can I just tee off without anything clever? The F and R are 15mm. There is 22mm right next to them, but I'm pretty sure the are only 5m run of pipe from the boiler and I'm not sure of the impact of messing with that.
Thanks for any help.
