STIEBEL ELTRON's latest range of hot water heat pumps, the WWK 222|222H and WWK 302|302H, set a new benchmark for heat pumps in the Australian market. Not only are they great looking but there are many new innovations incorporated in the sophisticated design. The great new features include a maintenance free current impressed anode, active defrost for operation down to minus 5°C, the option to connect the heat pumps with solar PV systems and the ability to transport them horizontally.

The WWK 222/302 H hot water heat pumps have a smart element situated in the top of the hot water cylinder. This smart element will switch on along with the heat pump function when a high volume of hot water is drawn off from the hot water tank. This smart element will assist the heat pump to heat approximately the top 80 litres. This smart element function is designed to aid hot water recovery for high use of hot water.
The WWK 222/302 (H) hot water heat pumps have an active defrost function that switches on when the frost monitor detects a build-up of hoar frost at the evaporator. When frost is detected, it will switch the fan off but will keep the compressor running. Hot vapor is directed to the evaporator and the condensor is shut off, this hot gas will begin to actively defrost the evaporator.
Yes, the H-models, WWK 222 H and WWK 302 H, are heat pumps with smart elements. These models have a 1.7 kW element that when engaged will heat approximately the top 80 litres of the tank.
Yes, these tariffs are ideal for maximum savings.
The heat pumps have an active defrost function that can control any icing that occurs at lower air temperatures. The active defrost function will remove any hoar frost that occurs at the evaporator and then reverts back to hot water generation mode.
2.3 Amps on 240 Volts
The new heat pumps have an encased compressor design to reduce noise. They are operating at only 45 dB. Heat pumps do make a sound when they are operating which is the sound of the compressor and fan. The noise from a heat pump is dependent on a number of factors, we encourage our customers to read the operating and installation guide to also take into account the positioning of the heat pump when installing.
The condensate drain and the top of the condensate pan should be checked at least monthly to remove any blockages that may have occurred via debris.
Yes, these heat pumps have been designed to be installed either indoors or outdoors. A clear space of 13 m3 is required for indoor installations to allow for the cold air from the refrigeration system to diffuse.
The WWK range of heat pumps are not designed for room heating applications. STIEBEL ELTRON have a range of air source hydronic heat pumps in addition to geothermal hydronic heat pumps designed for hydronic heating.
Rebates and financial incentives are offered Australia-wide at a Federal and State level depending on the type of water heater that is being replaced and what type of new system is being installed. It is extremely beneficial that you have a good understanding of what rebate is offered to achieve the best savings possible.
As of January 1st 2011, there have been changes made to the existing rebate scheme (REC) that was previously in operation.
A REC from a heat pump installed before the 31st of December 2010 has been reclassified as an LREC, or Large-scale generation certificate (LGC).
A REC from heat pumps installed on or after the 1st of January 2011 has since been known as an SREC, or Small-Scale Technology Certificates (STC).
Small-scale Technology Certificates (STCs) are an environmental type of currency which are issued after installation of water heating, solar power and any other renewable energy technology which helps to reduce greenhouse gas emissions.
Small-scale Technology Certificates prices are market-based and will fluctuate depending on supply and demand. There are a number of STC trading companies that you can compare pricing through.
