I have put up with having a warm air system for almost 2 months now, and it is rubbish! it warms up very quickly, but the house cools down at an alarming rate (though a lot of that will be put down to poor insulation). What really bugs me is that my room is quite far from the system & by the time the air gets to my room, it is cool...not nice when you are up 6.45 on a frosty morning!
I am now ready to put money down on a new setup. My choice is between a combi boiler and a typical hot water cylinder setup.
I am in a mid sized (ie 3 double rooms) semi-detached house, with a large open plan lounge/dining room and down stairs spare room, 7 rads & a towel rail. I don't use much hot water at all, but for future resell value someone else might. I don't use the heating much either (I can see my breath atm, and am feeling quite toasty with a jumper on) but again future occupants might. I do have a bath but don't use it much, I also like quite a powerful shower (who doesnt?). I also have very poor water pressure, something around 10L/min and every quote I have had so far recommends the smallest combi boiler they do.
The latest guy who came out (he has an awsome repuation) advised against a combi boiler, saying they were designed for flat originally and with such a low water pressure I would be better off with a cylinder system. The others (random companies I have found online) are quite happy to advise a combi boiler, but mainly because I suggested that to start off with.
The issue is I don't know which to go for. The hot water tank etc is more expensive but I am not too fussed with this, it is the running costs I am more concerned about. I know a hot water cylinder will be more to run...but no one can give me a definite figure to work out if it is worth it or not.
On the off chance someone on here knows their stuff with heating systems...can anyone offer any suggestions?
