How much do you actually save by zoning off upstairs and downstairs on a combi

[LGriffiths]

Hi all

Just debating whether or not to zone my heating upstairs and Down? It's gonna be a new install and the house is under 150m2 but just wondering how much you would actually save on the gas bill as to whether its worth doing

Thanks in advance

Probably not that much, it's probably going to come down more to how much control you want over your system. Then you've got to think about future maintenance as eventually, the zone valves will fail. If it was my house I wouldn't bother as I think trvs give you all the control you need.

I’d be looking at cavity wall and loft insulation, double glazing and good quality exterior doors first, stop all that heat escaping before thinking about zoning.

Thanks for the reply...
The house has cavity wall insulation,
300mm loft insulation and newly installed double glazing windows and rock doors

Honestly I think most people would have them on the same times anyway, during the week especially. On for a couple of hours before work then on for the evening after work. When you get home you want to get changed have a shower etc you want the whole house to be at the desired temperatures.

If you have a huge house then yes it's different you main have your main living areas and rooms that are used occasionally and that's when zoning a property becomes worth it.

you guys are right it's just more components to fail and cost money I suppose I just needed to hear it from other engineers

Best way to save money is to hide the timer where Mrs G can’t find it, also never teach the kids how to override the heating.

Hopefully going to install nest so if that heatings on when I'm in work il be turning it off over the phone

I thought you always have to zone each floor for regs.

In my opinion if you fully balance your heating system using lockshield valves no trv and have a manual heat setting on your boiler and maybe a honeywell froststat placed in the coldest position in your home set to 3 deg above zero
you really cannot go wrong oh and a basic timer
I will wait for the comments ...

or get a pre pay gas meter to make them realise how much stuff they are getting thro...
then it hurts

loft insulation is cheap at this time of the year I always buy now...gnomebase is in dire straights and all that stuff is rock bottom price...get in there before they go bust again
ok they have panic bought bathstore but still a business going down

Isnt it in the regs to install trvs on a new Install?

of course it is, but I am supplying the real logic, I have been in this industry which I love since 1982 and am a now
a designer of HVAC combi system boiler components ..so I tell it straight....look beyond the regulations if you want I do

Only if the size of the house exceeds 150m2

i have never turned my TRV's down i fit them but think they are a waste of time. especially if you have weather comp

I thought that was the old reg, isn't it now upstairs downstairs zoned but on a single programmer with two stats under 150m2, then twin time clock and two stats over 150m2

I thought they did change it to that but then a few years later went back to under 150m2 it wasn't required to zone?

Oh wouldn’t it be nice if we were just allowed to use common sense.

It used to be, not sure when it was changed but documents from 2010 show the 2 zone rule where ones in 2014 show how it's dependant on dwelling size.
