Caleffi 535 Series Pressure Reducing Valve
The water coming from the mains supply in New Zealand is generally too high and variable to be applied directly to domestic house systems. Pressure reducing valves stabilise this pressure making the water suitable for use around the home. The Caleffi 535 series of pressure reducer valves makes it easy to get the pressure perfect with an easy adjustment dial and indicator screen. Once set the valve will continue to keep the pressure at the correct level until next adjusted. The internal cartridge, containing all the regulating components, comes pre-assembled as a ‘self contained unit’ to facilitate inspection and maintenance operations.
Caleffi 523 Series Tempering Valve
A tempering valve ensures that water arrives at your tap or shower at the perfect temperature every time. It delivers this constant temperature even when there are temperature and pressure variations in the hot and cold supply that are being mixed. This particular range delivers a very high level of accuracy and stability of temperature regulation and has been designed for houses which are likely to demand high flow rates.
Pexal Macro-composite Pipe System
This pipe system has been formed by encasing an aluminium pipe within two layers of cross linked polyethylene. This combination of materials gives it the heat retention advantages of plastic and the noise minimisation strengths of metal. A complete range of forged brass fittings can be crimped into place using stainless steel sleeves. This pipeand fitting range can be installed directly into the ground, concrete slab, within wall cavities or on the building envelope exterior.
Fondital Tahiti Gas Boilers
These gas boilers are Italian made and will perform at over 90% efficiency with very low emission levels and near silent operation. They are easy to use, reliable and safe. Some of the models incorporate condensing technology which further reduce fuel costs and decrease polluting emissions.
Ferroli Diesel Boilers
These boilers use a three pass heat exchanger which makes them over 90% efficient. They are also very clean, with air emissions exceeding strict European standards for air quality, as well as being very quiet. Their front access design makes them easy to maintain and clean.
