Fothermo aurinkosähköinen lämmitysvastus lämminvesivaraajiin

The Fothermo photovoltaic heating element enables easy photovoltaic retrofitting of your existing hot water boiler.

• Innovative MPP tracker
• Easy installation
• No registration required

The innovative photovoltaic heating element is simply screwed into the standard 1.5" thread and enables you to use solar energy for hot water preparation instead of conventional gas or oil heating. And best of all: no registration is required because the heating element does not feed into the power grid.

• Easy retrofitting
• Quick installation
• Patented MPP tracker with 99.9% efficiency
• Integrated reverse polarity protection
• Digital display
• Retrofitting via plug & play

The installation of the photovoltaic heating element from Fothermo is very easy. The photovoltaic heating element is simply screwed into the standard 1.5" flange of your existing hot water storage tank and the PV modules are connected via simple plug-and-play MC4 connections in parallel. The heating process then starts immediately and since complicated wiring is avoided and the voltage level is below 50 V, no electrician is needed for installation. The heating elements can also be easily combined with the Fothermo switchover device. The water in the boiler is then heated preferentially from top to bottom, and excess energy is fed into the house grid via the micro PV inverter on the switchover device.

• Hot water supply through solar power

Especially in summer, you can do without inefficient gas or oil heating for hot water preparation by retrofitting. Instead, enjoy your shower heated by the sun and contribute to reducing CO2 emissions. Thanks to the innovative MPP tracker, you also secure 50% higher yields and get the maximum yields from your PV modules even in bad weather. The heating element allows connection of up to 2000 Wp photovoltaic power, while the maximum heating power is 550 W. This means that the hot water supply of a 2-person household can be almost completely covered in the summer half-year at a maximum water temperature of 65°C in drinking water systems or 85°C in decalcified heating systems.
