Let’s break out the differences between a hot water boiler and a steam boiler to help you make an informed decision:

There are pros and cons to either a steam boiler or hot water boiler. The choice for your company is dependent upon your needs and goals.
Let’s talk about how both of these systems work:
Steam boilers incorporate a float valve and sight glass to automatically control the level of the water. Steam is distributed in the building by means of radiators. And by utilizing the effect of gravity, it is eventually returned back to the boiler. The whole process repeats without any special control mechanisms such as circulators, flow check valves or automatic bleeders.
Hot Water Boilers require specialized fittings and accessories to ensure they work properly. One of these is called an aquastat. The aquastat controls the temperature the boiler operates at and it also is a low voltage transformer and relay that controls the circulator. If more than one circulator is used, then multiple relays or control panels would need to be used. There is also a regulator that must be employed. In hot water boilers, regulators are special valves used to control the water pressure. There is also a check valve or backflow preventer. This ensures that pressure doesn’t escape from the hot water boiler back into the water supply, possibly causing higher pressure levels than is allowed in domestic systems. There is also a temperature-pressure release valve that ensures the system stays within maximum limits. Also, an expansion tank is needed for the heating and cooling effects that are applied to the system. Air bleeders also need to be incorporated into the circulatory system of a hot water boiler, and because the water needs to be circulated, a motorized pump is usually incorporated. There must also be a means of heating the water. A tankless coil can be immersed into the water, or a hot water maker can be used.
