Water-to-water heat pumps supplied from closed earth loops are ideal heat sources for low-temperature hydronic floor-heating systems.

There will always be fringe markets for products that use renewable energy to provide marginal heating comfort. These markets survive because early adopters willingly sacrifice superior comfort as the perceived price for using renewable energy.

Radiant floors don’t necessarily have to feel warm to work properly.

This established technique doesn’t always receive due consideration.

Software can help the hydronics professional design and install better systems.
