Advice on a digital room thermostat

Pincher

1. Air in the radiator: bleed air.

2. Balance the radiators: adjust lockshield valves of ALL the radiators.
Each radiator has an inlet side (heats up first, manual valve or TRV), and an outlet side (lockshield valve).

The hot water from the boiler is lazy, so it goes through the easiest and shortest path back to the boiler. This means the farthest radiators don't get much hot water, unless you redress the balance by narrowing the lockshield valves of the nearest radiators.

3. Sludge build-up. Top half is hot, bottom is cold or lukewarm.

Various ways of dealing with it. Always make sure you have a filter like Magnaclean or TF1 installed, otherwise loose sludge will go straight to the boiler, clog up the heat exchanger, and it gets ugly.

If you have to ask, you can't deal with the sludge yourself.

Radiator is on 5 in bedroom. Hottish radiator in the bedroom but the main one in the lounge is hot hot. At the mo, I'm not setting times on the boiler to come on and off but got going with a temperature on the thermostat.

So turn it up to 18 when I'm in, 10 when out during the day, 16 when I'm out in the evening, 10 when asleep. Radiators in lounge, my bedroom on 5 (max.) Bathroom, spare room, kitchen on lower. Don't have heating in hallway or on stairs. Don't know if bills going to be horrendous though...

Also, if away on hols what would you set the heating to? If away, I can set times on the dial on the boiler to come on and off and just one temperature on the thermstat only. What would you set the radiator dials to as well?

IS your loft well insulated ? Do you have cavity wall insulation?
If not you will find this makes a huge difference to warmth and bills.

some good advice here - can i put my dilema to you all?

i have an old house, that is centrally heated and double glazed. timer on the boiler (can't do diff times for diff days), thermostat on boiler for adjusting radiator and water temperatures. room thermostat in hallway and indiv ones on radiators. btw i've got a combi boiler (unfortunately not a condensing as plumber talked me out of it).

i need to heat the house for prolonged time during the day and evening. which is the most economical method ? - as far as i can see it, i have 2 options:
1) to have boiler thermostat set higher and for it to come on and off during the day (unfortunately when it's off downstairs temp drops quickly due to orig floorboards with gaps) OR
2) to have boiler thermostat set lower and have it on for longer periods.

Is there a big cost difference? - really cold winter last year and got a shock when bill came in.

Look at the dozens of other threads asking this question. The longer you leave it on, the more it will cost.
Why don't you seal the floorboard gaps? An easy DIY job.

Yes, need to look at loft insulation made need topping up. Apparently I have cavity wall insulation.
