In colder regions and during winter seasons, hot water becomes a necessity for us. That is why several households use a Domestic Hot Water (DHW) system. A DHW system delivers hot water to the kitchen fittings and bathroom fittings and accessories, such as showers, faucets, baths, etc. Generally, these heating systems provide hot water through a centralized storage tank. Stiebel Eltron, a German renewables expert, provides high-quality and versatile heat pumps that can be connected to your photovoltaic system. The brand focuses on delivering top-quality, sustainable, and smart heating and plumbing solutions. Furthermore, the company is one of the top suppliers of technology products for building services and green technologies worldwide. They believe that electricity harnessed from renewable sources is the energy of the future.

 

DHW heat pumps by Stiebel Eltron

The Domestic Hot Water heat pump is a thermodynamic heating system. It is sustainable because it can convert environmental energy into heat used for heating water. It can draw heat from various natural elements such as water, ground, and air. The heat drawn from the environment is then passed through an evaporator from where it is fed into the heating system through a condenser. This appliance generates heat by using five parts environmental energy and one part electrical energy. This small portion of electrical energy pumps the environmental energy to bring its temperature to a level suitable for heating.

This compact appliance has a metal casing specially designed for garden installation. It will assure dependable functioning and long service life while supplying hot water to multiple draw-off points throughout your home. You can also install this heat pump indoors in recirculation air mode. It can even generate its own solar power and use it for heating water. Furthermore, a photovoltaic system can be conveniently connected to the heat pump. The benefits of the heat pumps are discussed below –

 

Sustainable and effective

Sustainable DHW heat pumps by Stiebel Eltron use free environmental energy for heating water. These systems work by drawing heat from indoor air. For example, the basement is an area that often gets unintentionally heated because of boiler or electrical appliances. In this case, the DHW pump reclaims this energy instead of allowing it to go to waste. It is significant to note that up to 70% of the energy requirement of DHW can be sourced from recirculated air. In fact, when operating on green electricity the appliance has no CO2 emission. Therefore, the DHW pump is a convenient and environmentally friendly solution.

 

Affordable and hassle-free installation

A Domestic Hot Water heat pump comes in a compact size that can be installed with minimum effort. The appliance comes fully wired and only needs to be connected to the water pipes to operate effectively. The heat pump comes with a fan and collects warm ambient air from the atmosphere and extracts latent heat from it. This latent heat is then used to heat domestic water.

These compact DHW pumps have the capability to supply water to numerous draw-off points. A maintenance-free impressed current anode built into the equipment avoids the need for anode testing making it cost-efficient. Installing this appliance will give savings of up to 50% in heating bills even when the outdoor temperature is -20 °C.
