Conservatory Heating

boogiesherbs

Hey all im stuck what to do about the lack of heating in Conservatory with winter fast approaching and little girl using as playroom.

1) Put a CH radiator in there? +Cheap to run - Wont fire up as it will be colder then where thermostat is.

2) Put an electric heater in there + more thermostatic control - a fortune to run?

Any help greatly welcome !!:):)

How do you work that out?

Not quite correct assumption especially if the radiators are individual thermostats. However, what could happen is that the boiler may not switch off because the radiator thermostat in the conservatory will not switch off, possibly leaving the rest of the house very hot unless individually controlled.

How do you work that out, it will not matter what the radiator TRV's are set at if the main room thermostat switches the boiler off, they only control the temperature of the individual radiators.

Sorry - I think I didn't phrase my previous comment very clearly. What I meant to say is that you will need to have the main room thermostat set to a high temperature so that the radiator in the conservatory reaches the set temperature before its TRV sets it off. But I don't know if this will then turn the boiler off.

Yeah sorry my Thermostat is on the landing that controls when the boiler clicks on,

The TRVs on the radiators just control their temp when the boiler is on,not to switch the boiler on,

A single oil filled radiator is a possible solution.

Any idea how much they cost to run mate?

During the winter have your little girl play in the living room or a bedroom which is already being heated rather than heating an extra room purposely as a playroom would be the true money saving answer to your question.

Any idea how much they cost to run mate?

Depends on how much it consumes and how long its going to be running, not to mention how high the thermostat is set!.

As a rule of thumb a 2KW heater will consume 2 units (+2 digits on your meter) for every hour it is running. At 12p per unit (example) it would cost 24p an hour to run. A 3kw heater will use 3 units per hour, which at the same unit cost would be 36p per hour to run.

In practice, after the first hour or so, the room will have heated to the temperature which the heater has been set to, and the thermostat will click on/off in relation to the ambient temperature dropping in order to top up the fall in temperature, and so the heater will no longer be running and consuming current continuously. Of course how often the heater automatically switches back on, depends on the size of room, air movement (doors opening / closing) and how well insulated the house is.

That said, make sure the heater(s) are adequate for the size of room. Many people think that they can heat a large draughty front room requiring 6kw of heat 'input' using just a single 2KW heater. In reality you cant get 6kw of heat from a device producing just 2KW, so the temperature in the room never gets to the thermostat setting and the heater does consume electricity continously and the room occupier still feels cold!.

I am trying an Air Source Heat Pump (also chill too) will see if its viable this year.
Its a Daikin 3.4Kw but hopefully will not use that much for most of the time as it has a COP of 4 I think which means if conditions are right it will use less then that . It cost me £700 to buy and install so not cheap.
Lots of threads on this site check them out for more info if interested.

That is easy to work out - then you set that against the capital and running costs of extending the house central heating system.

I have an electric convector/fan heater in my conservatory - I'll be dead and buried before I would recoup the cost of extending the central heating
