hi newbie here,
the council put in a new valliant boiler, cylinder and new rads throughout as part of the homes standard they have to adhere to these days. I'm disabled and live in a small bungalow so it's only 3 rads and hot water. i don't have a bath, the shower is electric and heats itself, so the hot water to kitchen and bathroom hot taps should come from the valliant boiler. the old larger twin panel rads have been replaced with smaller single panel rads. the replacement cylinder is a surprise as i was told during design stage that i wouldn't need one, i'd just get a new boiler (used to be a back boiler on the fire). Why is there a cylinder (1600x300 hw & top immersion heater) on this system and is it interfering?
principally, i want to try and work out how efficient my system as it's using more gas and the heating is poor without it being really cold. there should be heat available below a certain level of cost, if not there's either a faulty setup or design flaw, so i'm dubious about whether this setup is fit for purpose. can anyone help me defunk my brain about what to investigate?
the boiler is a Valliant ecotec plus 615 which the installing engineer said exchanges heat or something, and CAN be cheaper but depends how it's used.
on the design sheet that the heating engineer did for my bungalow, there is a graphic table with the rooms, rad sizes and types, trv's, and a column that says load (no units specified). what do you think this could mean?
i've found the manufacturers radiator specs (myson HE), and the load quoted on the design sheet is more than the maximum output for each radiator he quoted. i wondered if load meant what the engineer had calculated the required heating output to be for each room? the fact that the load on the table is larger than the rad max output, but considerably smaller than any wattage i get from a radiator size calculator is a bit worrying. do you know if they take things like furniture into the equation when calculating room heating requirements or is it mostly cubic size?
eg, if i said my bedroom was 4.1x3x2.4m, south facing with one single glazed window the load next to the rad he's specified is 767 (no units). the max output of the rad he's chosen is 660w. the wattage i get from a calculator is 1183. that's a big difference.
the lounge specs are out too- load 1691, rad output 1463, approx calc wattage 2000w.
does this sound wrong to you too?
finally, and sorry this is so long, how do i work out whether it's cheaper to have the boiler at lower or higher temp setting to maintain thermostat setting? it burns at both and i'm not sure how to run it economically.
appreciate any help thanks
