Making money and improving sustainability with an electric boiler

Due to increasingly higher natural gas prices, the industry is looking for alternatives. At Zantingh, they are seeing a growing interest in Varmeteknikk’s range of electric boilers. Since increasingly more green electricity is produced in the Netherlands, the imbalance (difference between supply and demand) on the electricity grid is becoming greater, which means that electricity can be purchased under attractive conditions in times of surplus. Companies that already have a heat buffer and a heavy grid connection can take advantage of this, become more sustainable, achieve climate goals and significantly reduce costs.

In order to quickly absorb peaks and troughs in green electricity production from sun and wind and convert them into useful energy, further investment will be required in flexibility, and the greenhouse horticulture sector is an ideal scenario for this, says the burner specialist. The sector can quickly change its production capacity with CHP or use an electric boiler and convert ‘power’ to ‘X’ in the form of heat. In greenhouse horticulture, many growers have large heat buffers, and the heat produced can easily be stored and used in the greenhouse for most of the year (including at night in the summer months).

Negative electricity prices
A substantial grid connection is required to install an electric boiler of any capacity, which is already there on farms that have heat/power coupling. In the Netherlands, declining or even negative electricity prices are increasingly common on the spot market. Especially in the spring and summer periods, when the demand for electricity is lower and the production of solar and wind energy peaks. Negative in this context means that the consumer receives money for the electricity they buy and consume in the relevant time slot. In combination with algorithms available on the market that can predict grid imbalance prices with increasing accuracy, more electricity can be purchased flexibly and at very low costs.


In combination with CHP
Application in combination with CHP is even more interesting because, for example, self-produced electricity can also be used, and the heat supply on farms with gas-fired boilers, geothermal energy, and heat pumps is becoming increasingly hybrid. Price incentives in the form of temporarily high or low, sometimes even negative electricity tariffs, help with this, and by cleverly and lucratively controlling devices on an imbalanced market, a lot of money can be saved!

Zantingh says that an electric boiler has many more advantages, such as being easy to install, very efficient, with very flexible control, rapid response to heat demand, sustainable, and low maintenance costs.
