Bought a green/leed certified home

Moving to an area in newmarket that have green and leed certified homes.

The home has a combination boiler + hydronic air handler to heat the home and provide hot water. Anyone have this setup? Thoughts? I can see they are big money to replace when they break down but appear to be super efficent and quiet.

Also has solar panels system to heat hot water. Cistern that collects rain to flush toilets and irrigation.

OMG why would you do that? Just from your description it sounds like 10x more headache vs normal house. Now you can invite Greta Thunberg for some smokeless tofu bbq.

What headache? From what? Lower energy bills?

What makes you think it's electric?

OP, Pretty cool house. It's too bad the gov't doesn't make better insulated and higher efficiency homes the minimum standard. It would barely add anything to the crazy high prices we pay for homes.
I especially like collecting the rainwater to flush toilets.
It's a nice setup, hopefully it's reliable. But it's still probably cheaper than renting standard equipment like so many people do.

Because it's got solar panels to power it and a gas boiler as secondary source

Why is it a headache?

Do you use electric baseboard heaters, knob and tube wiring and lead pipes with appliances from the 50s because it's simpler?

Might be vapour barrier on the other side. It’s how we did our cottage basement to r45 (propane heat).

Based on the pics it seems that there is a vapor barrier between the roxul and the pink batt. My point was that roxul or batt should always be covered with something. Be it drywall, plastic or whatever.

I admire you for a LEED house. I think if it was the standard, the present value of reduced energy consumption should pay for a lot of the additional building cost, if not exceed it. I'd go solar but the roof of my house doesn't face directly south and the previous owners' choice of concrete tile roof make it a bit difficult.

I did a housesit in an older Vancouver house that was refitted with a gas boiler for the radiators, which through heat transfer heated the hot water. Not so green but that system needs calibration and maintenance which the home owner never did which resulted in the boiler going INOP during our house sit).

OP, I think that house sounds super cool. I'm pretty jealous. I do wonder if the replacement cost of the high-end technology is worth the cost savings, but just using less energy to life your life is neat too. I don't have a house anywhere near that efficient (and wouldn't unless I tore it down and built another one), but have done a few upgrades and it's definitely improved the comfort of the home, cut my energy bills, and helped out the environment a little.

Does the solar produce electricity or does the solar produce hot water?

Solar hot water heaters make a lot of sense though our climate requires some care in design and installation so it doesn't freeze. I presume your heater uses a "coolant" or heat transferring liquid that doesn't freeze even at extreme winter temperatures?

Anyone who has a swimming pool would do well to have solar heaters.
Canada is so behind in home standard.... flushing toilet with fresh water is insane....
Lots of countries like that, where water was once plentiful bu becoming less so. Some municipalities where I am fear running out of water during a dry summer.

Correct. Glycol filled to ensure it doesnt freeze.
