Heat Pump Hot Water Cylinders – The Ultimate in Cost Saving

Imagine if you could save up to *80% of your hot water heating costs, rain, hail, or shine… The average Auckland home spends about 30% of their energy costs on heating water for the home. What would the savings be for you, if you could save *80% of one third of your power bill.

A word of caution on Hot Water Heat Pump Systems

There are many different brands of heat pump hot water cylinders flooding the market, however if I was you, I would be very careful when choosing which one is best.

Some models claim to be super efficient, however I can honestly tell you from experience that cold showers soon take the shine away from the savings if you buy a model that just doesn’t perform as it should.

Which are the best Heat Pump Hot Water Cylinders

Before you decide what model is best for you – you first need to be sure about how much hot water you are going to use per day. You need to be able to store a large volume of hot water if you use lots of hot water as recovery of the hot water is slower than traditional electric hot water cylinders. Some of the models that claim extreme efficiency, are a little misleading – they do not tell you as an example that it will take 11 hours to recover a full tank of hot water. Yes very efficient but you end up with no hot water to do the dishes at night… It could be very frustrating.

The Rheem Heat Pump Hot Water Cylinder is Preety Good

Heavy Duty Heat Pump – The latest generation in electric water heaters (hot water cylinders). The large 310 litre storage capacity and increased recovery rate of the Rheem heat pump hot water cylinders is excellent. The Rheem heat pump hot water cylinder uses approximately 1/3 the amount of electricity of a conventional electric water heater. Saving you up to 2/3 of your hot water energy cost. The economical Rheem Heat Pump uses ambient heat from the atmosphere as its primary energy source. Advanced single-pass top-down heating technology delivers hot water to the top of the tank, heating the tank from the ‘top-down’ and providing usable hot water faster. Fast recovery rate minimizes Heat Pump operation, extending product life. Packaged as two separate components and connected during installation for simpler handling, delivery and installation.

How good is the Ecoplus Hot Water Heat Pump System?

According to Glenn – Brilliant!

Hi guys, Many thanks for a job well done. The job was done to a very high standard by guys obviously at the top of their game. Kinda cool hearing tradesmen singing while they work, and the mood well reflected in the finished product. The pipework, wiring, isolating switch and finished job look exceptionally tidy compare to what it replaced. Was a nice touch being shown the completed installation by tradesmen, with a quick explanation of form and function (when they finished). I am amazed by quietness of the unit during operation and the functionality is almost unbelievable. Just (5) minutes after initially turning system on, the water coming out of the tap was warm enough to have a shower (no wonder the claim 80% savings). Will be interesting to see power bills going forward compared to the more expensive solar system it replaces! And almost forgot to mention, our shower pressure has increased post install – another plus!

Cheers Glenn, Kingseat, Auckland
