A rated House with Gas Hob

magnethead

Just wondering if anyone has experience with a Gas Hob in an A rated house? Thinking of putting in a range master with gas hobs, electric oven in. Would this over heat the place
I see a lot of these houses going for the induction Hob, much more efficient.


Edit:
Eventually found one thread where the owner doesn't seem to have an issue with a range.

Every house built in the last 10 years (well the vast part of) is A rated and I’ve seen gas hobs in many of them.

Suitable ventilation is all that’s required.

The only reason you see induction is because the builder only has to run an electric cable into the house then, no gas feed and the associated additional cost to that and the site.

Thanks I'll worry a little less now, I have HRV installed (Pipes anyway) and a powerful extractor right above cooker, venting directly through the wall.

If decent airtightness is achieved which I would assume if 'A' rated, be sure you have a window close to the hob extractor that you can open a crack when using the extractor.

Thanks Mick, (0.9 on the prelim airtightness)
Is that so the 850m3/hour extractor doesn't unbalance the ventilation system? Is that much of a thing? Some HRV manufacturers say it doesn't affect the ventilation, but I'm with you, it probably does, Will be testing out the theory hopefully in the next 3 months.

Do you have experience needing that cracked window ;p Mine is 3M away, but quite large, 1.5M wide tilt and turn.

Hi, What would be the reason for needing to open a window while using an extractor? Not something I’ve heard before or seen being done.

Yes, air tightness less than 1 m3/hr/m2 and the effectiveness of the extractor significantly improves when a window is cracked open. The air has to come from somewhere!! Might depend on who's cooking too:rolleyes:

This was part of the window design ... openable section closest to hob/extractor.

In an airtight building, you need to supply external air for the extractor to work efficiently. Unfortunately, it's often overlooked because it is a relatively new concept (air tight buildings, that is)

Our house is A rated with a gas hob. We were given an option of Induction/Gas and we opted for gas hob. Extractor fan is always on when cooking. Happy to answer any question you may have.

Thanks for the explanation.

We are actually planning to fit both induction and gas hobs. I’ve seen it in a house recently with 4 induction and 4 gas side by side (separate systems, not a combined unit) and looked the business. Great to have the back up for when power goes etc and I’ve always cooked with electric and my wife with gas so nice to have both options.

Overkill surely.

Using a gas hob isn’t difficult!

Hi, Yes probably a little but we are going overkill in a lot of areas of the house so not afraid to push things out a little (if we do decide to do this). I’d be happy with a 4 induction and 2 gas but I don’t see any options for fitted gas hobs in a 2 config (and I want it to look well which it might not if it’s not symmetrical).

Do you leave the window open when using the extractor and how big is the kitchen/open area roughly

Thanks
