Can your cylinders work with hot water heat pumps and solar panels?

Our standard cylinders are “solar ready” which means they are ready to be used with an energy saving device such as a hot water heat pump or connected to a solar system.

If in the future you choose to upgrade to either of these energy saving systems then you will have the right cylinder for the job, with no expensive modifications or add-ons. A very nice piece of future proofing, and one of the main reasons we recommend HJ Cooper cylinders!

How do I choose a hot water cylinder?

Dramatic improvements in technology over recent years mean that hot water cylinders are much more efficient and reliable than those of days gone by.

There is also a much wider range of models and sizes available. It is important that you select the cylinder that is going to meet your needs, both in the short and long term, so that you’ll always have plenty of hot water. Talk to The Cylinder Guy about your needs. Think about how many people the system will have to service; a household’s usage of hot water cylinder varies widely, depending on the age of family members, and the appliances used in the home. Consider also what energy source you wish to rely on. While most people opt for the mains pressure hot water cylinder option, we are also able to supply hot water cylinders that are suitable for low-pressure uses.

Can a new cylinder save me money?

Did you know that in the average NZ home 1/3 of your electric power bill is consumed in hot water heating?

So replacing an inefficient older cylinder with a modern one will probably reduce your power bill. So will switching from a big cylinder to a smaller one – which can make sense if you had a big family but now the kids have left home. For real savings, though, we recommend installing an Aquafire heat pump.

What’s the cheapest way to heat my hot water?

Installing an Aquafire heat pump will save 60% of your hot water heating costs. In a typical household with an average monthly power bill of $300 you can expect to save $60 a month, which means you can expect very fast payback on your investment. An ideal time to upgrade to a heat pump is simultaneously with the upgrade of your hot water cylinder. Click to this page for more information about Aquafire heat pumps.

What are the signs a hot water cylinder needs replacing?

Don’t land yourself in hot water. Cylinder problems and failure to identify them early can lead to considerable damage as a result of the slowly leaking water cylinder or sudden failure of a hot water cylinder and flooding. Sometimes problems with a hot water cylinder go unnoticed for a considerable time. It’s important to check your hot water cylinder on a regular basis.

What kind of cylinders do you use?

Whilst we service, install or replace any type of cylinder, we recommend the New Zealand made HJ Cooper cylinder range with stainless steel lining and Rheem hot water cylinders.

The HJ Cooper Cylinders lined with the highest quality duplex stainless steel and guaranteed for a market leading 20 years. This ensures a long life, durability, light weight and increased corrosion resistance.  HJ Cooper Cylinders are available in a range of sizes to suit any home or business, and offer low and high pressure options.
