What is the profile/thickness/rating of the studded insulation?

The insulation layer is 25mm and the circuits are 16mm diameter, hence 41mm together. Therefore, you should allow at least 50mm for the screed above the circuits, so a depth of at least 90mm is required and you can apply more screed up to 60mm with total height of insulation + circuits + screed up to 100mm. The pros/cons of less/more screed are:

  • Less screed will be more responsive to initial heating/cooling
  • More screed has more thermal mass to radiate/absorb heating/cooling into the evening

What does a typical screed installation looks like?

You can either create depressions in the structural slab for the screed layer clear of fixtures such as walls, island bench, cupboards, etc, where you want the heating/cooling to be located, or alternately, you can run a screed layer over the whole of the structural slab but you will need to insulate the slab edges otherwise you will leave a conduit for heat loss/gain in winter/summer.

Is the higher cost of heat pump compared to gas boiler worth it?

The capital cost of a hydronic heat pump solution for heating and cooling, using water as the heating and cooling medium, will always be more expensive than a gas boiler because of the greater complexity of the heat pump. However, it does give you reverse cycle cooling also in summer that is very effective in a well-designed home in a southern or inland climate where humidity is naturally lower. 

Different methods to heat a bathroom sustainably

The bathroom in your home has different heating and ventilation requirements as compared to the rest of your home. In temperant climates, it is one of the coldest parts in the home. In this blog, we would recommend different methods to heat your bathroom "sustainably".

Heated Towel Warmers:

Towels warmers are available in different shapes and sizes, making it the versatile, space saving choice for bathroom heating. In addition to heating up the room it also adds certain aesthetics to the bathroom, typically for modern, minimalist or contemporary bathrooms.
