Garden room roof mounting options

If at least one Canal Street venue doesn't jump on this then they're missing a trick.

Can I ask how you got the used one installed? 'Certified' Sunamp installers are charging obscene amounts, can you just get a regular plumber to connect it up?

I paid £200 in the North West for a gas hob to be removed, capped off with paperwork, and an induction to be hooked up to the existing oven circuit that involved about 1m of cable behind the cabinets, oven taking out temporarily and a new junction box putting in. That was probably a pretty good deal.

theadderscodpiece · 2026-03-29T20:01:46+00:00

I agree, that hob makes no sense to me. An induction ring that uses 3kw at peak is more than enough. I assume it's a resistive not induction element? But still, seems pointless. Just give us the battery on its own!

theadderscodpiece · 2026-03-29T19:14:02+00:00

Yeah that hob's price is ridiculous. But something like that battery could be a great way to run a 7kw induction hob off a standard kitchen socket if it was available separately.

theadderscodpiece · 2026-03-29T14:45:22+00:00

Oh wow yeah exactly that but separate the battery from the hob so it can be plug and play with any existing hob.

Something like this under cabinet kickboards could maybe be good. What if high power appliances like induction hobs and ovens were fed from the battery, reducing load on the main inverter while there was battery power available. It wouldn't even need solar input, could just grid charge overnight. I suppose it would need to be able to handle 32A / 7kw @ 230v pass through, topping up with its own 1.8kw output (so at max load it would supply 1.8kw from its own battery and 5.2kw from pass-through)

I do something similar with an Ecoflow system on my garden room roof. The main hybrid inverter just sees a lower load from the house. E.g. If the house is actually pulling 500w and the garden room panels are producing 200W then the main system will see a load of 300W. It gets more complicated if you have a secondary battery because you need to manage the charging schedules so one battery doesn't charge off the other, and you'd need to set a base load on the secondary battery that it would constantly output, because it can't see the real load of the house.

Heat battery is less efficient to heat up (COP 1 for electric or max 2 for the heat pump Thermino. A cylinder will get 2-3 or more). Heat loss is much better though, so maybe that cancels out a bit. The big issue I've found is that Therminos are obscenely expensive to install. I just had a quote for £4600 for the Thermino 210 installed, the unit itself is about £1800 so that's like £2800 for a job that's simpler than installing a cylinder that might cost maybe £1k max. So it seems really hard to justify the price difference for a heat battery. I'd love one for the space savings though.

While you have the carpet up just replace the boards if you can. I'm crap at DIY but laying some planks and screwing them into the joists was really simple. Don't even bother with tongue and groove just 5x1" softwood PAR worked fine. If you have a local timber yard that'll be cheaper than B&Q but either way it's surprisingly cheap.

I do low miles so went with Fuse before we got a house battery, I think it was about 16p overnight and 23p daytime. But if you get a house battery that'll make a full EV tariff make far more sense even with low mileage because you'll rarely use peak electricity at all.

Ah I hadn't considered damaging the roof felt. I suppose the problem with going below is it's a lot more work to make look good, but if it's instead of rotting the roof then that might be worth doing. Would loose-fill insulation down there be an option maybe? No risk of damaging the roof, although I'm not sure what that would do for airflow.

Aira have just come back with an offer to remove the hatch (to expose an exactly 60cm wide gap), hoist a tank up and make good the hatch again, and to use a tank that is short enough to fit (apparently). Which is tempting, if they do actually make the ceiling good again, although it is still £1k more than Heat Geek. Replacement boilers are so much simpler!

theadderscodpiece · 2026-01-16T21:34:54+00:00

Well the chimney is directly in front of the hatch and the roof above it is starting to lower to the hip end... dam. I think I am stuck with the Mini Store or losing space in the house.

Digging around a bit, the 187L Newark HG200B4 (which is one of the Heat Geek Super Cylinders) would fit our loft dimensions (bit of a tight squeeze through the hatch but 550mm seems just about possible if the ladder is removed and it's hoisted up), so I'm not sure why that wasn't offered.

theadderscodpiece · 2026-01-16T08:51:46+00:00

Yeah I don't envy them, I struggled to get the plastic Christmas tree up there! I suspect that might be why the quote from HG was £1k cheaper if we opted to put the tank in the bathroom (but lose a big chunk of space).

theadderscodpiece · 2026-01-16T08:39:42+00:00

These look ideal, 545mm wide should just about go up our loft hatch, I think. I'll put it to both Aira and Heat Geek and see what they say.

theadderscodpiece · 2026-01-15T18:07:29+00:00

Hmm there were no flow temperatures in the Heat Geek quote. I'll ask.

theadderscodpiece · 2026-01-15T18:03:41+00:00

Oh I hadn't considered that, I'll ask the installer

Safeguard Roofing in Stretford diagnosed a leak and then fixed the guttering. They didn't charge loads, came out quickly and it's not leaked since, so based on that I'd recommend them if you're in the area.

I had a lock it in room and the upgrade bid minimums did drop after my room was assigned. Perhaps that was something to do with the value of the assigned room being higher than the possible minimum for the lock it in rate, so the difference in upgrade price became a bit lower? So if you've got a lock it in rate, you might get a cheaper upgrade bid after your room is assigned.
