17. Protecting the Boiler against Accidental Overheating
There are several methods that can be used to secure your boiler against unwanted overheating. You can either connect a cooling
heat exchanger protecting the system from overheating by using Danfoss BVTS, Honeywell TS 130 or WATTS STS 20
connected to water supply piping. In the event you use your own well, you can protect your boiler using a backup electric power
source to sustain the operation of at least one pump. Another option is to connect the boiler together with a cooling tank and an
inverse valve.
