    got to be gas wall heaters as mentioned above


    so easy to fit and if you dont use the system then no harm will come to them

    just run your gas pipe to the correct depth and sixe easy peasy


    done something similar for a customer but the heat was for a greenhouse far far away and i used 28 mm pipe in case he upped the usage :LOL:

    Good point Slogger,
    on a second thought, I'll be digging the trench anyway (mains, waste) I can add 28mm pipe for the gas too, then isolate it both ends in case I decide to use it, no harm right? If I used pipes to feed remote radiator, then as chrishutt pointed out I'll need the frost controll too. In the case of this winter, few months around zero, that system would have been running throughout the winter regardless of the room being used or not.
    I know its called a summer house, but I'll probably use one room as an office on a regular basis.
    To correct previous assumption, its not wooden, but brick.
    Thanks for your feedback guys, I have a better idea now. ;)

    Most of the gyms I've used have been unbearably hot and I'd always choose the running machine close to the A/C blower. Therefore...have you considered a heat pump. It runs on electricity but costs about the same to run as gas because for every kW of electricity used it gives about 3kW of heat to the room. Heat pumps also double as A/C units for the summer and cost considerably less than the other solutions to install.

    ...however... if you're thinking of expanding to a heated swimming pool you might want to lean towards getting a new gas supply down there and install a second boiler at this stage, though if it's an outdoor pool used only in the summer months solar panels will be the way to go for pool heating, sticking with the heat pump for the space heating/cooling

    Hm, I didn't know what heat pump was, so I had to quickly check it out on howstuffworks, it seems a good idea, but I still cannot fully understand how to compare kW of electricity to kW of heat. This is heating engineer's job, or google check may do it too, but overall its an idea worth considering....so in fact it is more efficient A/C unit, nice.
    I like greener stuff... :LOL: In fact if we had more sun in this country I would cover all my roof areas with solar panels. Its amazing how much free energy we have around us, we're just having trouble collecting it and there's the big apple. ;)

    It depends on the system and the operating temperatures.

    The ground based systems often give you 3-4 kw of heat output for the consumption of 1 kW of electric power.

    Its a high capital cost system and in my view rather questionable if the pay back is taken into account if the alternative of gas or oil is available.

    Globally its not so eco friendly because electricity generation is only about 30% efficient where gas use is now 93% efficient.
