As time goes by, many habits change but the need to have sanitary hot water (ACS) for personal hygiene and that of our homes remains unchanged . The increase in prices for the supply of energy and traditional fuels leads families to always seek new solutions to optimize costs and consumption.
To meet these needs, different solutions have been developed not only for reduced energy consumption but also for low environmental impact. So let’s see what are the alternative systems for producing domestic hot water.
Alternative systems for producing domestic hot water
Although most families use the gas boiler to produce domestic hot water, today the trend is to use alternative systems. These include heat pumps, thermal solar panels, biomass boilers, natural gas boilers, condensing boilers. Let’s briefly see how these systems differ.
Heat pumps are one of the most innovative, efficient and environmentally friendly systems for DHW production. There are various types of heat pumps that make it possible to generate accumulations of domestic hot water. Heat pump boilers use a heat exchanger fed by a fluid. The fluid takes heat from a cold source and extracts it by conveying it to the exchanger. Heat pumps save up to 70% of electricity and ensure optimal performance even for air conditioning.
Solar panels exploit the most natural and free source of energy, that of the sun . The panels convey the solar energy to a boiler for the accumulation of sanitary hot water that transmits it to the hydraulic system present in the house. If the accumulated energy is not enough, it is possible to support the panels through the installation of a domestic hot water generator. In order for their operation to be correct, it is important that the panels are mounted with the right direction and inclination.
Pellet boiler and biomass boilers
If it is not possible to install a photovoltaic system, the pellet boiler is another good solution for DHW production. This boiler, in addition to having optimal performance, has high thermal efficiency and is able to guarantee uniform heat throughout the house. Compared to traditional wood-fired boilers, biomass boilers automatically load the fuel supplying superheated water during all hours of the day. These generators require a storage system , as they still do not allow instantaneous preparation of sanitary water. For this reason, the most congenial solution is to combine the biomass generator with a solar thermal system thus further reducing consumption and consequently also costs.
Natural gas boilers for hot water
The natural gas boiler is one of the most common solutions for the production of water for sanitary use and for heating the house. These boilers have low costs and high efficiency.
Condensing boilers are becoming more and more popular, replacing the old gas or natural gas boilers, thanks to a system of government incentives and the system that allows a greater quantity of latent heat produced by the fumes to be exploited before they are expelled. Condensing boilers can either be equipped with accumulators or produce hot water instantly.
Hydrogen for DHW plants
The last frontier of domestic hot water production is the hydrogen boiler . Hydro is the first boiler that uses hydrogen present in almost all substances to produce electricity and hot water. Designed and produced entirely in Italy by E.HY. Energy Hydrogen , this boiler is available in various models and can be combined with other hot water and energy production systems ( more information on the site www.idrogenoverde.it ).
How to choose and install alternative systems for ACS
Alternative systems for the production of domestic hot water can replace existing systems in the home or building or be combined with them to improve energy efficiency, reduce consumption and make up for a greater need. The choice therefore varies according to the systems already present and / or the needs.
Today it is possible to benefit from numerous tax deductions for their installation. An experienced plumber will be able to advise which system to choose, in compliance with the existing regulations for their assembly and maintenance.
