I am moving in to a new flat 1 bedroom. 4 radiators, Worcester 24cdi combination.
The problem is that for now there is no room thermostat and no trv on the radiators. For the next month or two It have to stay like that. Latter I will be able to change, add parts to the system.
What will be the best way to save energy in the main time.
- I have manual clock on the boiler so I was thinking to set the CH to go off for 15 min every 30 min or set it to 15min on 15 min off. In the morning when I start the system I will set it to work for one hour and than again 15 min on 15 min off.
- Or The lower the temperature of the water in the CH system let's say to 50 and not to max witch is 82
Also when I will do I change in the system what will be the best way ? TRV on all the radiators or room thermostat ? I can have only one of them. (money ? )
You're supposed to have both on new installations, with the thermostat in the hallway ( usually ) near a radiator with no TRV. You can buy a cheap but effective three-wire ( better than two wire because a three-wire thermostat has a slightly more predictive capability ) TRV's for £12 at B&Q.
Anyway, if I had to go for one option I'd personally go for TRV's on all rads. In that case you need to make sure the CH boiler has a bypass valve, since once the TRV's all shut off the boiler will be trying to pump hot water into a completely shutoff system, and it needs a short bypass loop and valve to allow water to continue to circulate back to the boiler ( the boiler senses return temperature, so if there is no flow 'cause all the TRV's are shut off the boiler will go a bit mad ). If the boiler doesn't have a bypass valve you need to fit one or leave a TRV off one radiator.
Of course, in that case that radiator always be on at full blast when the boiler is on but you could always throw a towel over it to reduce output if that room gets too hot.
