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?

Hydronix supplies products for hydronic underfloor heating using air-water heat pumps.

Four times the efficiency. Now most luxurious. Now least expensive.

This is the modern way of Underfloor Heating, or In-Slab Heating.  This system gives the same most luxurious comfort as the old direct electrical wired way.  But, at about one fourth the running cost.

Even undertile and undercarpet systems still run at that old efficiency of 1kW of heat energy for each 1kW of electrical energy.

Now modern air to water heat pumps generate about 4kW of heat energy for each 1kW of electrical energy.  That’s right, four times as much.  The heated hot water moves the energy very effectively to your floor slab.

This method will definitely give you the most comfortable heating for your new home.  And it will deliver it at the lowest cost of all.  Our hundreds of clients can tell you that.  We don’t know of any who would ever have their house heated another way.

To mesh or not to mesh

February 9, 2018

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