Hydronic Home Heating Design Services

hydronic-heating-1Hydronic radiant heating is the ‘Rolls-Royce’ of heating. Hydronic heating features are:

  • extremely efficient
  • whisper quiet
  • relief for allergy sufferers due to low air movement
  • able to be the domestic hot water baseline heat source
  • optionally heat the swimming & spa
  • fast heat up
  • energy efficient
  • panel radiators and/or concrete slab radiators possible
  • $1000 per radiator (example below is 18 panels)
  • slab heating is approx $50/sq metre

Cost estimates for a 35 square house with 18 separate panel-radiators is $1000 per panel. This includes the complete hardware system: panels, water heater & burner, pump, water supply valving, piping & thermostat. This does not include GST or plumber installation labour.

The total heating power for this 35 square space is 22kW or 80,000 BTU. A spreadsheet with price breakdowns is available after contacting Kroll. <Click Here> for a generic hydronic plan for a 35 square modern home which shows all system details.

Adding domestic hot water requires a low pressure water tank (with heat exchange coil for the mains-pressure water supply) and an extra pump & pipingswimming-pools-1

RB20 Pellet Burner by Kroll

Kroll is releasing a new wood pellet burner fitted to the Kroll cast iron SM8 hydronic boiler. This system is expected to be around the $8500 mark, depending on options. The system includes the 20kW RB20 pellet burner & boiler with pellet auger. A 50kW & 70kW version is also available. Another option is the best of both worlds: pellet burner plus a Kroll BR10 burner, each fitted to their own hydronic boiler.

New Kroll Boiler Control

Save Energy with Kroll Boiler Controller

Kroll has a new boiler control designed to reduce electric power consumption to the absolute minimum needed.

Bearing in mind customer sensitivity to the environment & massively rising electric power rates, Kroll has an ‘Energy Save’ boiler control now as standard.

If the heat load request is OFF the boiler and burner consumes zero electric power.

The control itself consumes a minimal 2 watts of power in ‘Energy Save’ mode.
