Adding small radiator, cost

borderline

My bathroom doesn't have a radiator, the boiler guy was surprised I didn't have one, I live in rented accommodation and heating is included in the bills. Landlord was present when boiler guy recommended the radiator. They are going change the boiler and he said it would  be very easy to install a small radiator in the bathroom, Landlord didn't seen keen on that.

will having a radiator in the bathroom will add much more to the gas bill? well, considering the landlord rations the time the heating is on , he doesn't want to spend a penny extra

Yes, adding another radiator will increase your gas consumption. By how much depends on the size of the radiator and whether a TRV is fitted. Picking a radiator at random - https://www.screwfix.com/p/flomasta-type-21-double-panel-plus-single-convector-radiator-500mm-x-500mm-white-1960btu/411xp - Assuming a flow temperature of 70°C, it would add an extra ~570W to the total load on the boiler. At lower flow temperatures, the load would be lower.

I have a total of around 11kW of radiators, so adding that particular model would increase my maximum heat demand by ~4%. Would probably add 2-3% to my gas bill, so fairly insignificant.

If this is self contained accommodation, presumably you are paying the utility bills - If so, why is the LL rationing heating ?

If you are paying for what you use, why does the landlord limit heating times? Or are your bills included with rent, so extra cost would go to the landlord.

A little but maybe not as much as landlord perhaps it seems seem to fear.

Assuming that warm air from other rooms het by other radiators is already freely circulating to heat unhet spaces like the bathroom the difference will be small.

Essentially other radiators will already be supplying that circulating heat.

But chances are the bathroom will be a little hotter - directly heated - which is actually msybe a very good thing in other ways - like good way of you and the landlord avoiding potential damp and mould issues in what is often the dampest room in the house.

Unless you are really time constrained on boiler up time and don't use TRVs / thermostats in practice to limit the overall power consumption from the boiler / and cummulative radiator nominal ratings - most wouldnt worry about their max ratings.

(More of an issue if house cannot achieve set temperatures consistently due to undersized rads and lossy construction)

As in most homes max boiler powers are only used in the first 1/2 to 1 hr of firing daily - and after that initial heat up from cold - modern boilers will quickly derate (restrict gas flow to drop power) and/or then mark space on off on burner - and radiator trvs or thermostat will cut flow when rooms or master thermostat reach setpoints.

Infra red wall heater £20-30 to buy and economical as only turned on when needed, I wire in my own but you would probably have to add electrician's bill if in rented

yes, self contained, gas is included in the rent, that's why the landlord dictates when and for how long the heating is on .

yes, gas included in the rent, that's why he is stingy with the heating

The bathroom doesn't get much heat, there is just one radiator in the living room, it's a small studio but in colder days the bathroom is cold. A radiator in the bathroom would be welcomed, but landlords don't want to spend extra money, do they?

It may not use much extra gas, as technically the other radiators in the flat won't need to be as hot. It may enable the boiler to run at a lower temperature too so boiler will can run more efficiently. Depends on lots of factors though.

Just curious, does your rental agreement state that the landlord can decide when you have heating, maybe set hours that are written into the contract?

I could understand there being a thermostat fitted that limited the temperature but if it simply states that heating costs are included in rent, surely they can't turn the heating on and off whenever they want.

Is the elec included also? just use a small heater outside the room.

If your a tenant and not a room mate in his house then you should have 24/7 heating under your control.
