I just was reading about hydronic heat pumps because I wanted an all inclusive option. Thanks for covering them - always great hearing what Ross has to say!

We have an air to water heat pump in the UK, doing DHW and heating, via radiators. It saves us 25% over the traditional gas boiler we used to have. We added 10kW solar in March and now we are using 20-25% of the total electricity from the grid that we used to, and on sunny days are exporting surplus electricity raising credit to pay for our winter bills when the system will need more energy to run the heat pump. It's been a massive game changer.. our house has never been more comfortable, and is really good for the environment. We now only pay a couple of pence (cents) per day for gas, which is only used for some stovetop cooking.

I love love love my air source heat pump. It works completely independently until it hits about -12ºC (10ºF), after that point it needs a little bit of help.

That works out to needing the backup heat (resistive electric) for only about 100 hours over the course of an entire year, in Canada. The huge bonus is my house is nice and frosty all summer long.

Tommy what works great when you need to shape the filler and it may be vertical use parchment paper on the outside to form it. The filler sticks to the parchment paper before hardening but once it hardens the parchment paper peals right off. Thank you for your many years of helpful advice! Larry from Little Chute Wisconsin.

I work on the railroad and we use a product called spikefast and it is a 2 part epoxy that is fairly thin and fills voids in the railroad ties. Sets up in minutes and is very durable and can be sanded and drilled. Sticks to anything and needs very little prep

I’ve been watching TOH for a couple of years and never knew Ross is Richard’s son

Bondo for concave repairs, liquid wood and wood epox for convex repairs. One part filler for nail holes and nothing more.

Anyone know how hot the water/glycol mix is coming into the house? Has to be pretty hot if it’s going to heat and domestic. Or does the basement unit also heat?

[henryostman]

In cold and dark upstate NY, I doubt if solar will be much help in the long and cold winters, even if the panels are not under two feet of snow.

Hi TOH, me & my twin sister turned 58 years old today 😊

[saulgoodman]

Geo thermal, air to water heat pump, you'll never get your money back. It may save like 2k a year. But they cost 10's of thousands to install.

[jasonsgroovemachine]

I don't always watch TOH videos, but if it's Mark I do. I think it's because of all the things people do on TOH, masonry is something I do the least of.

[luckybestwash]

"We want to be sure the unit stays above the snow" uh in upstate NY that entire box will be covered in snow

[Datsun]

8:54 Those are goofy instructions but they are actually what Bondo says. Very weird. Inaccurate. They should just tell you what the ratio of the two should be. Bizarre.

From the Bondo site - "For a 3-inch diameter puddle of filler, squeeze out a 3” long strip of hardener. ".

They don't even say how thick the "puddle" should be. No way to be as exact as Tommy implies it should be. Less and more don't really mean anything.

[shanew]

If you have an extra $50k+ sure ill take a geothermal unit or heat pump set up like in the video 😂 most people don't.

[nickk]

They are lying it will cost twice that at today electric prices and then go up

[alias]

wow. imagine if we just produced more energy and didnt restrict it on consumers. this junk wouldnt be around.

[nickk]

Heat pumps are still very inefficient under 32 lol
