As the innovative continuation of Guangdong Shenbao Electrical Appliance CO., LTD, which was established in 1999, with rich experience in manufacturing and exporting air to water heat pump products. O.S.B. have born in 2014, dedicated to provide the highest quality of service and most demanding products available in the latest market.

Up to now, we have equipped with 3 automatic production line, 3 cold/hot condition enthalpy testing lab , fully refrigerant auto-refilling machine , as well as all necessary testing equipment, such as 4-in-1 electricity safety inspection machine and halogen leakage checking machine, etc. All management are executed by following ISO 9001:2008 system.

The heat pump products we have been manufacturing and supplying to Europe, South Africa and Asia are well accepted by the market and we have achieved more success by passing EN 14511, EN16147, EN14825 etc energy efficiency test , as well as our self developed IOT wifi control function that applicable in almost all of our air to water heat pump products.

We compete, we innovate, we welcome you to john us and be partner with us to make the best products!

1.ASK: Air to water heat pump is heating faster?

Air to water heat pump heating rate according to the water temperature and outdoor temperature

Summer inlet water temperature and outdoor temperature are high,so heating faster.

In winner inlet water and outdoor temperature are lower,so the heating is slow.

2.ASK: How much the air to water heat pump power consumption?

Mainly influenced by outdoor temperature.When the outdoor temperature is lower,the heating time is longer,the power consumption is more,and vice versa.

3.ASK: What does the air to water heat pump heating principle?Why can energy saving?

The refrigerant in the evaporator absorbs heat from the air in the environment. After the compression of the compressor, the pressure and temperature rise, the circulation to the heat exchanger to heat the water, then throttling set device to buck, evaporator to cool down,cycle again to the compressor.

This principle can be drawn: the air to water heater not use direct electrical heating water, but with a small amount of electricity to drive the compressor and fan, to act as a heat porters to heat transported to the water tank inside.

The energy of the electric water heater is composed of pure electric energy

The energy of the solar energy heater is composed of electric energy and solar heat.

The energy of the air to water heat pump is composed of electric energy and air heat.

Note: the difference in air to water heat pump and solar energy heater is that the air to water heat pump can not be influenced by the environment.

4.ASK: what conditions can not be used?

When the power cut off can be use a bucket of hot water for a while. And without water or the water pressure too low can not be use.

5.Ask: Heating capacity whether the bigger the better

Host and tank must match, host too large will waste resources,the pressure is too large, the operation is blocked. too small ability is insufficient,heating slow.

6.ASK: Is it easy to operate, have hot water at any time?

No longer need to be adjusted after the initial installation.Will work automatically to meet your needs.

After reaching the upper limit temperature, the heat pump will automatically stop and insulation,and the water temperature is maintained at 45°-55°.

7.ASK: Can it be used if it rains?

The air to water heat pump only influence of the outdoor temperature and inlet water temperature,not affected by rain.This is the most obvious advantages compared with the solar energy heater.

8.ASK: Why the air to water heat pump more expensive than other water heater?

Early investment, investment behavior of late recovery.
