i have a two family house and the upstairs is rented and on it's own zone valves but the same boiler.
i've been burning wood all winter and have had my zone turned off. i'm wondering if i can get away with just draining my first floor zone (isolatled with shut-offs), shutting off my bathroom and kitchen domestic, and just not heating the downstairs.
the tenant upstairs would still be heating. would this put a lot more strain on her heating, as if my downstairs is essentially outside?
my boiler is an old burnham jubilee oil-fired. it keeps the basement pretty warm.
my house is insulated with icynene top to bottom and is fairly tight but with old windows. i have a fire every two days usually and stay very warm.
so can i do this or do i need to run my heat while i'm away?
Which would be cheaper, setting the thermostat on the lowest setting, or coming home to a flooded house from burst pipes?
Why take the chance?
Heat rises so there heat is going to do little to keep your place warm.
the other issue is, basically the whole back of my house is not plumbed for radiators as i'v ebeen using the wood stove.
so even if i did run my heat it would do nothing fo rmy kitchen and bathroom.
so the question is, do i need to plumb radiators and run my heat, or just shut and drain my 1st floor?
how could anything freeze and burst if it's empty? meanwhile, the boiler is still running for the tenant so all of her plumbing remains warm.
