Infloor Central Heating

Sun Flow water-fed heated floors radiate warmth from the floor up as opposed to most other forms of heating that create a build up of heat at ceiling height - heat that has cost you good money! Radiant warmth heats the floor, the carpet, the furniture, the walls and you, rather than heating just the air.

Sun Flow floors operate at around 1/3 the cost of heating to the same level by conventional methods. When powered by a condensing diesel boiler, a floor system will operate at around 10-11 cents a kilowatt (November 2008), half the cost of winter electricity. While people often worry about the fluctuation in energy prices, diesel has actually been the most stable commodity over the last 25 years. Because we all operate our homes differently, the actual cost will vary from home to home according to the insulation levels and the lifestyle of the occupiers.

The Basic Principles


New Zealand's Only Fully Insulated and Thermally Broken Floor System

Warm and Cool endorses the MAXRaft Flooring System for use with its infloor heating solutions. MAXRaft is the country's only fully insulated and thermally broken concrete foundation solution. The MAXRaft system can deliver a R4.5 insulating rating which when combined with a Warm and Cool heatpump powered infloor heating solution can deliver unparalleled heating efficiency and cost savings.

Choose the Heat Source

Pair your Sun Flow radiant floor with a variety of different heat sources:

Heat Pump
(up to 400% efficiency)

Evolution Condensing Diesel Boiler
(+35% efficiency)

Granada Wood/Diesel Boiler
(over 2 ha area)

Ecomax Coal/Pellet Boiler
 

Serena Standard Diesel Boiler
(cheaper purchase)

Ecotherm Electric Boiler
 

Won't it get too hot when the sun comes out?

Sun Flow floors are installed with a variety of effective control systems. Areas are zoned, with each zone flow individually controlled. It is also possible to configure zones on the warmer side of the house separately from zones on the colder side to give greater control as temperatures vary in these different areas. Our systems also come with both indoor and outdoor thermostats to ensure that all the environmental conditions are considered. Response time for a hydronic floor is from 30 to 45 minutes.

Integrating Domestic Hot Water systems

When installing a heated hydronic floor it can make sense to integrate your domestic hot water as well, heating that from the same more efficient heat source. It will cost more initially to install a quality system but there can be some real benefits.

We recommend Duplex stainless steel cylinders, carrying a 10 year warranty. These are imported from the U.K. And are welded in a specialised vacuum plant to ensure high quality joints and connections. New Zealand cylinders are welded in natural atmosphere and can fail in a short time.

Duplex cylinders come with either one or two internal exchange coils. This allows connection to a floor heat source and a solar or wet back system, ensuring that your domestic hot water is also heated in the most economic way. Duplex cylinder still carry 2 electric elements if solar top-up or full electric back-up is ever required.

One system - many possibilities - just one agent

The Sun Flow system is the ultimate way to provide a fully centrally heated home at the best possible price. There is no need for additional heating systems. Condensation is a thing of the past; allergies are reduced through the reduction in dust mites and circulating dust that often results from air heated systems.

Warm and Cool provides a one stop design, installation and back-up service.

More than 25 years of experience and over 900 installations completed means that quailty and efficiency is assured from Warm & Cool.

SunTouch Under Tile Heating

The SunTouch floor warming system features an ultra thin this profile that allows for installation under almost any type of tile or stone, including retrofitting on existing floors.

SunTouch is economic to operate. In an average bathroom uses the equivalent of about 3 100 watt light bulbs - but only when you want it to. A variety of controls can be utilised including 7 day fully programmable thermostats.

The elements are reinforced with DupontĀ® Kevlar and are insulated with DupontĀ® Tefzel. In addition, the outer surface is tough Hylar.

An alarmed monitor is attached to ensure that nothing is damaged during installation. All power is supplied through an R.C.D. giving SunTouch the highest combination of safety features.

The perfect system to heat your bathroom, kitchen, utility room or wherever you desire warmed tiles, slate or stone.
