Do I really need a Navien CH-240?
Just looking for some input. I'm going to replace my old boiler and water heater soon. The plumber wants to put in a Navien CH-240. Now I'm no expert but I did the heat loss calculation for my house and came back with about 105,000 BTU for a standard boiler. I know the Navien is a Combi but the CH-240 is 199,000 BTU. Isn't that overkill? My house has one zone with 10 hot water radiators about 4ft each average. I ask the plumber to do the setup so I can add another zone for when I refinish the basement. But the basement is only about 500sf. Is the CH-240 a good idea or should I ask him to go with the CH-180? Thanks in advance
