In the market for a new hot water system? Welcome to yet another overloaded technical purchase you never thought would be so complex until you took your first few steps of inquiry. The upside is that Bosch are a fairly reputable brand in general hot water systems. Therefore, the question arises, how does their super energy efficient, Bosch Compress 3000 hot water heat pump stand up in the real world?
As one of the last few remaining European built hot water systems available, it’s inevitable to assume that the Bosch Compress 3000 must be good? Be warned, as with most technically superior products or energy efficient products, the Bosch Compress 3000 is not without its limitations.
Potentially the biggest limitation of the Bosch Compress 3000 or any Heat Pump for that matter is the operation temperature range. For many climates around the world this will be a non-issue, however, those which reside in areas with temperature extremes beyond the -7oC to +40oC the Bosch Compress 3000 will not be a good solution.
Here’s how the technology works. In the simplest terms possible, the Bosch Compress 3000 hot water heat pump extracts heat from the air and transfers that heat into the water. No solar collectors are required. However, when combined with a photovoltaic solar energy system, the solar panels can power the heat pump as the sun shines with exceptionally low power consumption.
Depending on your household, the next design feature is either a limitation or a bonus. The Bosch Compress 3000 is equipped with a 270L water storage tank. This is neither the smallest or the largest available in heat pump hot water systems. Bosch advise that this capacity is good for 3-4 person households. Realistically it depends on how long your like your household spends showering. Effectively minimising, if not eliminating associated hot water heating costs.
Smart Controls: Think of the Bosch Compress 3000 as one of the most affordable energy storage devices in the modern world. Better value for money per kW of energy stored use most lithium battery systems. As noted in the previous section, the Smart Controls on the Bosch Compress 3000 assist the end user to take advantage of excess solar power produced during times of peak solar energy production.
Noise Reduction: Just like an air-conditioner heat pumps make noise, for those in areas where noise sensitivity is an issue yet you still want to enjoy the energy efficient benefits of heat pump water heating, the Bosch Compress 3000 is equipped with a noise reduction mode. When activated this mode will result in a longer duration to heat the water capacity.
Booster: If you are on the fence considering the 270-litre tank may not be quite enough storage capacity, there is a good solution. The Bosch Compress 3000 is boosted by one of the more energy efficient electric booster elements at only 1.65kW. An average hot water system booster element is rated at 2.4kW. A 31% reduction in boosted water heating costs.
This is where the Bosch Compress 3000 excels. With a maximum heat pump consumption of a mere 600W. Considering this is a maximum operating power draw the actual operating draw is often considerably less, although very subjective to environmental surroundings.
Operating performance and energy saving ability will naturally be diminished when operating in boosted mode drawing a maximum of 1.65kW during the boosted period. Not to be discounted and as mentioned in the previous features section, 1.65kW is considered a very efficient boost draw from any hot water system for the same temperature.
Another layered technology guarantee which is never as clear cut as we would all appreciate. Although, when dealing with parts which operate with a water supply the biggest issue which will arise from a manufacturers perspective is the overall water quality of your local area. Although clean the water may contain elements which are detrimental to the service life of a mechanical product.
Therefore the Bosch Compress 3000 is equipped with a two part warranty:
- 2-year all parts & labour warranty.
- 5-year tank warranty (part only).
Additional criteria will always apply to uphold such warranties so ensure you read your area specific warranty documentation carefully. Adequately maintain the Bosch Compress 3000 and the life expectancy will well and truly surpass the nominated warranty period. Ask your installer for a maintenance schedule.
Depending on what region of the world you reside will affect the overall price of the Bosch Compress 3000. With it’s highly regarded energy efficient nature, certain governments such as Australia offer incentives of approximately $900 AUD for installing a Bosch Compress 3000 hot water heat pump, therefore fore reducing the cost.
With no clear set RRP due to region, transportation and installation variables, resourced information suggests that the Bosch Compress 3000 is likely to cost an end user approximately 2 x more than a basic energy intensive instantaneous or storage hot water heater including plumbing and electrical connections. Your specific installation will ultimately define the final price.
Bosch have produced an exceptionally robust product in producing the super energy efficient Bosch Compress 3000 hot water heat pump. The overall cost is likely to sway certain opinion as to whether it is a viable option. However those with astute energy consumption habits and a thriving solar energy system are going to love the ability to reduce their energy consumption habits further. A worthwhile investment if one possess a solar power system.
