I'm curious, does anybody ever heat other surfaces too? Like, I've long been wondering if it would be beneficial or just nice to add radiant heat to bathroom walls in addition to the floor. I imagine it could help keep it clean if it dries off very fast after a shower.
@@Ariccio123 We often have our panels installed in the walls for additional heat output, or instances where the homeowner wants to maintain their existing flooring.
Practically all new residential buildings in Estonia (both detached homes and apartment buildings) have underfloor heating. Air to water heat pumps used to be the most common option for detached homes but lately ground to water heat pumps have become more and more popular due to their higher efficiency, especially in really cold weather.

This is a fascinating build series, but Steve has a habit of speaking over the invited expert, relating meandering and only peripherally on-topic anecdotes from his own practice instead of allowing the audience the benefit of that guest's expertise. It's rather unfortunate. Case in point: Steve asked the mechanical contractor about the Mitsubishi heat pump system but never permitted much of a reply, hence we didn't get to hear many of the technical details. Yes, there's ample access space around the air handlers. Woohoo.

Question.. I'm working on a project in New Mexico. We plan on using an Arctic, air-to-water heat pump for our primary heating plant. They recommended a supplementary electric boiler for those super cold days... Is there any reason I cannot simply replace the hot water buffer tank with an electric water heater? 1, They're somehow cheaper than stand-alone buffer tanks. 2. They have a fu%*ing hot water heater built in!.. ??
This stuff is interesting but, ironically, far out of financial reach for most of the RUclips viewers drawn to this subject. In the future, it would be helpful to explain how these various systems might work in mid-priced homes, if at all. Said another way, if this is an item designed for luxury homes, say so up front. If you told me this was a $3 million+ home, I would not be surprised.

You should ask the Mitsubishi rep why the drain pan heater on the Hyperheat units runs anytime it's below freezing outside, instead of just when the defrost cycle is running. It uses almost 200W which seems like a big waste of energy.
Is the unit creating condensation that can freeze over when it's below freezing, or only during defrost? The basepan heater is there to prevent the water which is constantly dripping from becoming a block of ice inside the unit. The accumulated ice on the coil might only turn into water during defrost, which I assume is what you're thinking of... but the unit is constantly generating condensation whenever the coil temp is below the dewpoint of the outdoor air - you'll notice water underneath your heat pump even on days above freezing. The basepan heater runs any time that condensation could freeze in the unit.
I was running my Mitsubishi mini split in heat mode (just installed) when it was about 40° outside and the outside unit was generating lots of condensation dripping from the outside unit. The base pan heater needs to be on so the condensation it is pulling out of the outside air in heating mode doesn’t freeze in the pan. If it’s 20° outside the air blowing out of the fan will be close to 0° and condensation will be created.
@@epiphany6 when the air temperature is below freezing, the coil temperature is even colder. I haven't seen any dripping in those conditions until it goes into defrost mode and warms up the coil. Then all the ice melts and water runs off the coil. Yet the pan heater runs anytime the outside temperature is below freezing, even if the thermostat is satisfied and the compressor is off. It seems like it could run much less often. Maybe there are some conditions when water could freeze in the pan but not on the coil, but I haven't seen it.
I would prefer to talk to someone who actually installs/works on the hydronic…to hear information from someone who’s never installed it would be hard to respect

With the Warmboard Comfort System we handle all load calculations, flow rates, design the mechanical layout, electrical layout, etc. The Comfort System water temperature will modulate based on the information our INDOOR reset sends to our Smart Reset Controller (SRC). Analyzes every minute. We're so fast no outdoor reset needed. Indoor reset will create a more comfortable environment for the homeowner! Thanks for commenting!

There is more water volume than one tank can handle. We only have room for a smallish tank in the Warmsource, so the extra one adds more volume! Thanks again for commenting!
Outside pipes absolutely require insulation. Regarding indoor pipes.. insulation will improve performance for sure, up to the homeowner/contractor really! BUT at least the heat will be going into the home if not insulated
Yeah, bullshit that you are tapping into solar battery for electrical resistance heating boost in Massachusetts in December. And this is AFTER pulling power out for a Waterpak. That's what? 80 Amps @240v ? And Probably more. Just in heating requirements. With about 3 solar hours in the winter. Utter bullshit. It's mostly coming from the grid during that time of the year unless you have submarine batteries and 200 panels for a house that size.
I realize that, but what everyone here doesn't seem to realize is thatmany people are not comfortable on camera and need to be coaxed on. The result is that I ask alot of questions, and talk a bit to make them feel comfortable and not need to talk much - making them more comfortable

Great work guys. Here in the Netherlands hydraulic underfloor heating combined with a heat pump is very common and very efficient.
I totally agree but the word hydraulic is not interchangeable with hydronic unless your also hydraulically raising the floor and the temperature.lol😊

What should they have used to toe things together?
21:40 should have installed the branch box in a way that wouldn’t have that big oil trap underneath the branch box.
would these consume more or less energy to heat a home vs forced air furnace?
Better be less cause it cost top dollar.
Less energy since you have to heat floors to lower temperature. The less delta between outside air and required temperature of floor the higher COP
can u explain that if i was 5 years old@@andreycham4797
