Eternal hybrid: the world’s first and most advanced hybrid water heating system.
My friend showed me this product awhile back. This tank is a hybrid between tankless and old-school water tank systems. The advantages seem to be that water is hot more quickly because of the reservoir (although, you’ll still have the water that’s standing in the pipes be cooled down, so it won’t be completely instantaneous, I assume), then you have “endless” hot water as the tankless part kicks in. It also is cheaper to vent and you’re able to hook a waste-heat recovery system (like this) up to it, which intrigues me.
The biggest drawback seems to be the cost – depending on the model they run around $2500-3000, compared to a tankless that’s between $1000-2000. It does advertise the “green rebate” (30%) that many of these appliances are eligible for, but I assume a regular tankless would qualify for those, too. I’ll have to look that up.
Anyway, I like the possibility of pairing the waste-heat recovery system with it. That is a big plus to me. I also wonder about how the cost of installation would compare.
