Drilling through exterior wall to fit rad

[Murf520970]

I Agree but there does need to be a permanent source of heat as when it gets very cold like recently the conservatories sap the heat straight out of the house. So what's it to be radiators that may not get the flow they require, standalone gas which could have positioning issues due the flue and heat radiation or electric due to cost or portable electric . Think I will stop thinking and just ask them what they want

Your understanding does not go as far as you thought...

You have to be able to disable the radiator in the conservatory, not run it when the rest of the system is off. Think about it - Part L is all about energy conservation and not chucking out heat to the night sky in the middle of winter when the conservatory is not in use.

A TRV to control the conservatory radiators is accepted as being fully compliant with the requirements of Part L (and exemption to building control).

If one wishes to heat a conservatory in the absence of heat demand in the rest of the house (e.g. cooler summer nights for example) then using the main boiler for a single zone of only one radiator makes very poor economic sense - you are far better off using supplementary electric heating. A basic standalone convector will more than suffice in such circumstances.

Whilst I agree that a TRV goes a long way towards meeting the Part L requirement, I would be surprised if it was fully complient without a timer to turn it off at certain times.

Few conservatories with their high heat loss would be adequately heated with less than 3 kW of radiator and that is still viable to heat with a smaller heat only boiler. I agree that with a high power combi the situation might be questionable though.

Oh for god`s sake! just use a longer bit mate! if it`s gonna take 2 x 10mm pipes you need a 28mm masonry bit right thru, forget about flow/return pipes on top of each other it`s advice given from idiots who read too many books and don`t install anything.Go for the radiator that fits the nicest under where you want to put it, as long as it`s big enough in kilowatts to heat the room, get as big a kilowatt output as you can maybe a slimline double radiator.It`s not rocket science, it`s a steel panel filled with hot water, simples.

Are you Polish? just like to say how good your written English is for some one who has only been in the country for such a short time.
Many congratulations on your visa application.

Rads in conservatories rarely make sense. The heat requirement pattern is so completely different, a stand alone heater is generally the only sane option. Unfortunately, as a retro fit, the dwarf wall is generally a little low.

Thanks for the advice lads I will take on board all the comments

The 1000mm sds bits from screwfix aren't that expensive and very very handy to have around.

Think about it with this cold snap do you want the new radiator freezing !
cos its off ? Not saying I'd do this but easy isolation and draining of just that rad ?

Holes ~ you want two decent 8mm sds bits first one what 100mm next one long enough to go through total wall thickness. use short ones first drilling from inside cons to inside house once youve got these driled exactly where you want them drill all the way through then with longer bit,either get someone to hold a board where youre gonna break through or just ease off the pressure and break through gently as your drilling keep pulling the drill bits back out to clear the dust out of the way.

Then put a 12mm bit all the way through then you final finished size hole bit 18mm. simple bit longer but much much neater than banging a big drill all the way through in one go.
you could go for one of these http://smithsenvironmental.com/html/psu.html
fast heat up and comfy in there in winter !!!

Excellent advice thanks mate
