The heat source installed for a central heating system can be integrated with a domestic hot water cylinder. This heat source will offer a cheaper per kilowatt energy cost than conventional electricity rates.
The central heating system is designed to allow the diversion of heated water (from the heat source) to an internal exchange coil in a quality hot water cylinder. The large capacity of most central heating sources means that the cylinder water is heated rapidly and there is no detectable affect on the heated floor system.
SunFlow Hot Water Cylinders
Standard NZ stainless steel cylinders are welded in natural atmosphere, which degrades the stainless steel within the seams and joints. This can lead to premature cylinder failure and as a consequence, many NZ manufactured stainless steel cylinders do not carry a long warranty - typically 2-5 years.
SunFlow cylinders are imported from the UK where they are welded in a purpose-built vacuum welding plant. The result is that the high stainless steel integrity is retained in the seams and joints. But the best news is that SunFlow cylinders come with a full 10 year warranty (in the UK they have a 20 year warranty, so the manufacturer has high confidence in their product). We supply 250 and 300 litre cylinders with single or twin exchange coils and single or twin 3 kilowatt back-up electric elements.
You can choose cylinders from other manufacturers but heating system warranties will not apply if the cylinder is deemed to have contributed to any system failure.
