How much will I save?
A hot water heat pump can save you up to 70% of your water heating costs. Every household’s water usage is different so finding good, trustworthy information for your personal situation is important to help you understand all your options.
With electrical, gas, solar or heat pump hot water, there are so many options today. What are the differences and what is the most cost effective and environmentally friendly option for your family?
To find out your total savings it's important to compare the upfront costs (purchase and installation), annual running costs, and lifetime costs of different types of hot water systems.
In many situations a hot water heat pump system will be much more efficient than traditional electric or gas water heaters. Heat pump technology can heat up your hot water cylinder with just 30% of the energy, compared to other systems.
Heat pump technology works day and night, in all seasons and in all weather conditions.

Enjoy savings of up to 70%!
An average shower will cost you around $1*. With our heat pump technology we can heat up your water with 70% less energy - which means that same shower will only cost you 30 cents.

Eco friendly & long lasting
Is it a ‘green’ system? Yes, we think it is the most economic domestic hot water system currently available in New Zealand.
Why? By using the best materials we are convinced that it is a very long lasting system. That is why our hot water cylinders have a 20 years warranty and the outdoor heat pump unit has a 5 year warranty.
Unlike other heat pump hot water systems where you have to change the complete system, only the outdoor heat pump unit has to be replaced after its expected lifetime of 10 to 15 years. This reduces purchase and installation costs and also reduces the amount of waste. Economic efficiency = ((Purchase & Installation Cost) / Lifetime) + Annual Running Costs.
Other things to consider:
To really get the most out of your shower it might be a good time to upgrade your low pressure hot water system to a mains pressure system when you upgrade to a Calitec system.
Using less power is not only good for your wallet, it also helps reduce the emissions of harmful greenhouse gases in New Zealand.
