Heat and hot water included.tenant only pays electric.

Forgot to mention an entirely new high efficiency combi heating/hot water system with new baseboard throughout as well.

My friend researched various lock boxes but wasn't sure if the signal would get dampened or the heat / lack of ventilation might be a problem. 

Consider your personal items in your house, your appliances, heating equipment, air conditioning, shingles, plumbing and electrical supplies, car parts, are some of there components made in a country that has been affected by covid-19?

It covers plumbing, refrigerator, electrical, heating, water heater, oven, A/C, the dryer, and smoke detectors.

And you don’t mention whether the heating system is forced air or a boiler with radiators.

The boiler for the building's steam heating system just blew and it needs two sections replaced.

Direct Operating Cost Pass-Through EscalationThis type of rent escalation is similar to tax pass-through escalation, except that your rent increases when operating expenses like heating, electricity, maintenance, and security go up in cost.

So after some research with the furnace company, the zoning officer/building inspector, and another hvac installer the *new heating system has to be ripped out of the house as it was installed totally incorrect and is unsafe.

Also, we need to install insulation below the first floor due to previous tenants saying that the floors are too cold, and heating bill too high.
