Which modular contactor to choose for a 2 kW electric boiler?

Hello! Description of the situation. Installed mini heating of 3 bimetal radiators in 10 sections. A 2 kW heater is installed in the mini-boilers. I want to automate the operation of the boiler. H1M temperature regulator is available (parameters 220V 10A). I do not want to switch the heater directly through the temperature controller, because the latter is in Chinese design and does not inspire confidence. In this regard, the question arises of selecting a modular contactor (brand, model number and its technical characteristics). Please help pick up a modular contactor? Thank.
