My House is taking ages to heat up

Have a look at a plinth (or kickstrip) heater - They fit in to the space under the kitchen units and can be plumbed in to your central heating system as long as the pipes are conveniently located. A good one is not particularly cheap, but having warm air blowing across the floor makes up for it. Fitted one in my kitchen quite a few years back. When I remodeled the kitchen two years ago (was it really that long), the plinth heater was the only thing I retained. Got rid of the wall hung radiator and reworked the plumbing to suit.

Thanks we do have one but it’s just an electric one, frustrating as we should have plumbed one in when we had the kitchen done / moved the boiler etc

Just checked yep I only have a 28 kWh boiler. It’s not a combi etc but I do only have 15 radiators which it easily supports. All of them are hot apart from the one in our bedroom. I don’t particularly want to change it as it costs a fortune !

The fact your radiators feel hot isn't the only consideration - are they big enough? A cigarette lighter feels very hot, but it won't heat a room very effectively. ;-)

"Only" 15 radiators seems a lot for a 28kw boiler. I only have 8 rads for my 28kw boiler.

I'm not an expert, just making comparisons.

Thanks makes me feel better lol, with a 3 year old 16 is too cold. I need to look into the radiators and the balancing as the boiler is going full pelt and it’s a big boiler

An ambient temperature of 18C+ is recommended for living areas and of 16C+ for bedrooms in UK households. 16C+ measured in a hallway is very likely to represent a safe, healthy temperature in living areas and bedrooms. 20C in a hallway could easily mean living areas are overly warm.

Certain very vulnerable groups - poorly mobile/ chronic ill health/ very elderly - may need a warmer home than the rest of us. But healthy babies and healthy children are not the delicate flowers that many believe. Better the temp. is moderate and stable than veering between overly cold and overly warm, according to the experts.

If you have 'downdrafts' in individual rooms, address this with thermally efficient, properly fitted window treatments. Downdrafts are due to air circulation within a room and can make it feel much colder than it actually is.

HTH!

Is the 17C to 19C increase in your hallway? If yes, what temperature are you actually getting in your living areas?

In our old house if we set the thermostat which was in the hallway to 16 degrees then the living areas were a very comfortable 21 degrees plus. We turned the bedroom TRV's right down to keep the bedrooms cooler. But the hallway in that house was much cooler then the rest of the house.

In our new house we are still working out the best temperatures to have the thermostats set too. This house doesn't really have cold spots so the thermostat which is in the hallway needs to be set to the temperature that you want the room you are in to be at.

We have turned the kitchen TRV right down as the kitchen has a tendancy to overheat when we are cooking, but in turn this means that when we get home from work or get up in the morning the kitchen is a bit on the chilly side until we start cooking then it heats up nicely.

We currently have the hallyway stat set to 21 degrees in the evening (we have fully programmable timers so you can set different temperatues for different times of the day) so that the living room is nice and warm in the evening.

Our new house is super insulated so we have not seen the temperature in the house dip as low as 18 degrees yet but it would feel chilly at that temperature!

We have got 23 radiators on a 23kw boiler. I think the important bit is balancing them. You just restrict the flow to the rooms you use least thereby prioritising the flow to the rooms you use the most.

Thanks I have a large designer radiator in the bedroom, the valve on the right is red hot the radiator is barely even on, we’ve had it checked in the past and changed the valve but it’s made no difference, tried bleeding it makes no odds

They reckon only DIY experts have their system properly balanced because it is fiddly and plumbers can't be bothered. There are websites that cover the procedure.

You need to get more energy into the structure

Increase your min temp.

Our heating can warm up the air quickly but if I let the structure get down to 10c when away it can take 12hr to stability.

I set to 15c min temp unless away for extended period.
target 19c when in.

Yes I rented a cold stone-built house once, and with the boiler radiator temperature set low and running 24 hours a day with wall thermostat set to 18 C, it took nearly two weeks for the structure to warm up.
