SELECTING THE HEAT SOURCE

Select the best heat source for your project

WHY OUR HEAT SOURCES ARE SMARTER

At KE KELIT, we only design systems with energy efficient heat sources, so standard efficiency boilers and heat pumps aren’t part of our offering at all

Selecting the best option for your project requires an understanding of the home’s unique needs: what the homeowner's expectations are, the fuel that's available, the size and occupancy of the home plus more. Our inhouse, dedicated expert team will provide impartial advice on the options available.

Standard efficiency gas boilers can no longer be installed in Europe. In NZ they are still heavily promoted because of the perceived price advantage - but it’s a false economy.

Energy-efficient heat sources can reduce operating costs by up to 30% compared to standard efficiency heat sources. So, any increase in capital cost is very easily offset by reduced operating costs. To help achieve this optimal performance, KE KELIT Climate Control recommend the use of advanced European technology heat sources supplied by Viessmann.

Difference about the two heat sources condensing boiler and non condensing boiler graph
Condensing water heater how does it work

Condensing Water Boilers:

An energy efficient condensing boiler recycles hot gases by leading it past the cold heating water that comes back into the boiler.

How does a normal non condensing water boiler work

Non-Condensing Water Boilers:

A normal standard efficiency boiler directly heats up the heating water. Precious energy in the form of hot gas is wasted (it goes right up the flue).

VIESSMANN - VITODENS 111-W RESIDENTIAL CONDENSING BOILER

Rapid, reliable and compact, the Vitodens 111-W gas condensing boiler is a high-performance wall mounted storage boiler for family homes with a high demand for hot water.

With its cylinder loading system (CLS) and 46 litre integrated stainless steel storage tank, the 111-W has the capacity to fill a standard bath in just 8 minutes, whilst also supplying a sink or washbasin simultaneously.

As is the case with all Viessmann gas condensing boilers, the Vitodens 111-W is equipped with stainless steel Inox-Radial heat exchangers. This technology brings with it an extremely high-efficiency rate of 98% and exceptionally reliable and efficient operation during its long service life. Viessmann guarantees the Inox-Radial heat exchanger for ten years against leaks resulting from corrosion.

VIESSMANN - VITODENS 200-W COMMERCIAL CONDENSING BOILER

The Vitodens 200-W boiler is a powerful, flexible and easy to maintain wall mounted gas condensing boiler that is perfect for larger detached homes and commercial buildings.

Available as a system or combi boiler, the highly efficient Vitodens 200-W boiler is packed with features such as the Inox-Radial heat exchanger, colour touchscreen and is smart home ready, with the ability to be controlled remotely via an optional app.

As many as eight Vitodens 200-W gas-fired condensing boilers can be combined in a single prefabricated cascade system, with inputs up to 4240 MBH. As a cascade system, the boilers are staged to meet fluctuating heating demands, it maintains maximum efficiency by precisely matching the load. A cascade system can also prevent interruption of heating plant operation, with multiple boilers available for back-up.

VIESSMANN - VITORONDENS 200-T CONDENSING DIESEL BOILER

The Vitorondens 200-T diesel boiler is a floor standing oil condensing boiler with an attractive price/performance ratio. Its dimensions are impressively compact and it is particularly suitable for modernisation projects.

The sectional cast iron Eutectoplex heating surface guarantees high operational reliability. By ensuring an even heat flux, stress fractures are virtually eliminated. The wide water galleries prevent sedimentation and boiling noises. Flexible gaskets permanently seal the individual sections on the hot gas side. The horizontal layout of the hot gas flues also permits thorough and easy cleaning of the boiler.

As is the case with most Viessmann boilers, the Vitorondens 200-T diesel boiler is equipped with stainless steel Inox-Radial heat exchangers. This technology brings with it an extremely high-efficiency rate of 98% and exceptionally reliable and efficient operation during its long service life. Viessmann guarantees the Inox-Radial heat exchanger for ten years against leaks resulting from corrosion

VIESSMANN - RESIDENTIAL AIR TO WATER HEAT PUMPS

Affordably priced, efficient and easy to install, Viessmann air/water heat pumps are an attractive space-saving solution for making use of natural heat in family homes.

Renewable energy options are the future of heating and hot water in your home: clean, green resources that don’t run out and have minimal impact on the environment. Air to water heat pumps are a perfect example.

The Viessmann air-to-water heat pumps extract energy from the outside air in temperatures down to -15°C, so they are ideal for providing low-cost home heating throughout the year.
