central heating in conservatory

[wobblymike]

i intend to extend my ch into my conservatory and further intend to employ a professional to do the installation. I wish to use this forum to ensure I understand the process.

I have a vaillant ecotec combi boiler which is controlled by a danfoss tp5000si rf thermostat and rx2 switch.

I know what size rads I need and am in the process of purchasing them together with TRV and lockshields, second tp5000si rf thermostat to control the conservatory independantly, and a 2 port zone valve to isolate the conservatory.

The plumbing for the rads will be picked up from under the lounge floor and run into the conservatory to the 2 rads and back - my first question is where does the zone valve go?

Appreciate any guidance.

Just after you hranch off the flow to the conservatory

 

[GasmanxxxR1]

Or possibly on the return from it if its more convenient

 

[lame plumber]

why do you need zone valves, trvs will do, my only issue is why do you want to warm up a glass house, total waste of energy. conservatories are for keeping your pot plants protected in winter, if you need to stay warm put some insulated brick walls around you. One day people will understand why we are running out of fuel!

 

[Dannypipe]

This is the sort of job that would be best to let a professional assess the job first hand.

I personally like underfloor heating in conservatory's over rads. On the priviso that the conservatory will be in regular use over the winter, as UFH takes longer to heat the space.

 

[Dannypipe]

LOL - Some people want a warm conservatory LP.

I know it's a waste of fuel, but if you don't do the work, someone else will!

 

[GasmanxxxR1]

You need zone valves on them now to meet regs

 

[Dannypipe]

My current job is to construct and heat a conservatory BTW.

I should put up photos really.

We removed the old UPVC carbuncle. We've put in a 9m long steel, and have £16K worth of bifold doors going in. Triple glazed, the U values are amazing. We've also fitted 3 large Velux, double glazed, electric opening. Pretty good U values.

This room is sandwhiched inbetween 3 internal walls though.

Of course I'm fitting UFH with its own stat and controls.

 

[stoker122]

If you want to zone it independently you will need another zone valve on the heating so you will need to come off of the flow from the boiler. You conservatory valve will need to switch the combi so wiring back to boiler as well.

Planningportal.gov.UK states -

Building regulations will generally apply if you want to build an extension to your home.

However, conservatories are normally exempt from building regulations when:

They are built at ground level and are less than 30 square metres in floor area. The conservatory is separated from the house by external quality walls, doors or windows. There should be an independent heating system with separate temperature and on/off controls. Glazing and any fixed electrical installations comply with the applicable building regulations requirements (see below).

You are advised not to construct conservatories where they will restrict ladder access to windows serving rooms in roof or loft conversions, particularly if any of the windows are intended to help escape or rescue if there is a fire.

Any new structural opening between the conservatory and the existing house will require building regulations approval, even if the conservatory itself is an exempt structure.

Don't forget the frost stat or you'll freeze up in the winter. Don't fancy your gas bill though.

or anti freeze in your heating system, just isnt right tho!

Why employ a professional when you'll get everything you need to know on here?

It's one thing having instructions, but a totally different thing executing them 🙂

 

[Dannyparty92]

Well perhaps if he knew everything then he wouldn't have too get someone in ha. Also it may not be possible to pick up from the heat circuit under your lounge floor that maybe a leg that maybe need upsizing if you add an additional two radiators on that leg.

 

[jfb]

not install a small air to air heat exchanger

 

[jfb]

meant to say why not install a small air to air heat exchanger.

My reply was tongue in cheek. 😉

not to a conservatory, there should be no heat from your heating system to a conservatory to meet the regs. Unless it forms part of the house which would require planning permission etc......etc......

 

[SimonG]

Electric fan heater, instant heat when you are in there. Shut the door when your not.

 

[GasmanxxxR1]

not to a conservatory, there should be no heat from your heating system to a conservatory to meet the regs. Unless it forms part of the house which would require planning permission etc......etc......

Thought you could if it had separate time and temperature controls

 

[AWheating]

Thought you could if it had separate time and temperature controls

not what ive been told, by local building control, must be independant ie.... a speerate heat source like a leck heater. Different on newbuilds with planning permission already sorted i guess.

 

[Dannypipe]

On my current project, the heating has to have independant controls from the house system to comply.

 

[GasmanxxxR1]

But not a seperate heat source

 

[AWheating]

i dont know how its ever done even with planning permission, as new builds and extenstions are suppost to have good u values/ very small heat losses. your just wasting energy.

planning permission is needed if the doors between the house and conservatory are removed.

 

[GasmanxxxR1]

AW perhaps your local building control has interpreted the regs differently to others. Might be worth asking again if it crops up as a job for you

 

[Dannypipe]

It is a waste of energy, but then so is a house with no thermostat, and there are plenty of them in the country.

 

[GasmanxxxR1]

I think new conservatories have good u-values as they have polarised glass and all that

 

[Dannypipe]

Glass can only be so good, and it's never going to compare to a cavity wall, with Celotex inbetween.

But the doors going in on my project are as good as it gets. The U values are pretty amazing considering it's glass.

 

[AWheating]

i was told the same thing by nhbc inspector and on hetas training course, unless its part of the building (ie. no doors) it should not have a heat source connected to the system.

what i ment danny was if we are supposed to be building new stuff to high energy eff standards then why waste money on great insulation etc.... then throw heat into a conservatory. Im supprised its allowed. I know its done, just trying to understand why?

why spend thousands on energy eff stuff and allow it to be wasted in one room? whats the point of part l then?

I understand what you mean mate, and to a greater extent I agree with you....but I think it's good that we still have some choices we can still make for ourselves. Even if they are a waste of energy.

I guess the long and short of it is:

If you like having a bright room, with windows out to your garden, but want it to be at room temp so you can sit out there and sip your tea in comfort, then you are going to have to chuck some heat at it.

I know for those concerned for the environment it must look ludicrous! I'm half and half in the camp.

Would you feel differently if the room was heated by an ASHP or similar?

 

[lame plumber]

wear a jumper if you sit in a conservatory in winter. the human race evolved from furry critters and caves to living in nice warm houses, now the stupid ones are trying to reverse the process, should be made a hanging offence

im all for choice, and feel the same as you by the looks of it. you dont have a choice about alot if the building regs tho, most rules and regs are two faced at best. i guess there wont be much choice in 30-40 years. we will all be splitting atoms!

its not about how i feel, heat or no heat i just think the regs go one way and then the other.

Harsh but fair!

Best option fit a air to air heat pump will take care of heating and cooling, thats summer and winter covered.
If you cant afford this and must have heating fit a radiator and use honeywell Evo home to control and zone it you wont need the extra pipe work from the boiler to zone the system as the trv heads are self ectuating and this will zone everyroom in your house.
