We do hydronic underfloor heating

We do hydronic underfloor heating.

Modern underfloor heating systems either electrical resistance elements (“electric systems“) or fluid flowing in pipes (“hydronic systems“) to heat the floor.

4-1 Co-efficiency

Electrical underfloor heating use direct electricity, 1kw electricity produce 1kw heat energy. While air to water heat pump has 4 to 1 co-efficiency, which means using 1kw electricity to general 4kw heat energy, then put it into your slab.

Simplifying Underfloor Heating for Kiwis

Step 1: Put Hydronix underfloor pipes in your slab.
Leave no regrets from the start!

A concrete slab without underfloor pipes is a home with no future.
You can retrofit ventilation later. You can retrofit PV panels later. You can add a high-wall heat pump later, add a log burner later, add a radiator later.

But you don’t have the chance to put Hydronix underfloor pipes in again!

Let’s put the pipes in the foundation, leave an opportunity for future!
No consent required, one day’s work, we are here to support you, how much simpler can it be?

To mesh or not to mesh, that is the question. Should underfloor piping be installed onto the mesh, or stapled directly to the polystyrene?
