No heat, no hot water, or both?
Cold radiators, a boiler that will not start, and a cold shower need different checks. Tell us which problem you have so we can arrange the right service for your South Shore home.
The house has no heat
Tell us whether every room is cold or just one heating zone, and whether the boiler display shows a code.

Smell gas? Leave the house first, then call the gas utility or 911 from outside. Do not use switches, phones or anything that sparks inside the building, and do not go looking for the source. Call us afterwards, once it is safe, for the repair.
Why You Have No Hot Water
A loss of hot water can involve the heater, a shared boiler system, or a problem at one fixture. Diagnosis comes before a repair or replacement recommendation.
The fastest clue is what kind of heater you have and how it's failing. A gas tank gone stone cold points to the pilot or thermocouple. An electric tank usually means a tripped breaker or a burned-out element. A tankless error code gives the technician a starting point for diagnosis — write the code down. Here's how we think through it.
Common Causes by Heater Type
Gas tank: pilot or thermocouple
If a gas tank runs cold, the pilot may be out or the thermocouple that keeps it lit has failed. Sometimes a relight, sometimes a small part.
Electric tank: breaker or element
An electric heater with no hot water often means a tripped breaker, a popped reset button, or one of the two heating elements has burned out.
Tankless: error code or scale
A tankless unit usually posts an error code — write it down and check our Navien error-code guides. No code but weak hot water often means scale choking the heat exchanger.
Age & sediment
Heaters past 10–12 years lose capacity as sediment builds. 'Runs out fast' on an old tank often means it's time to plan a replacement rather than chase repairs.
What to Check First (Safely)
A couple of safe checks can save you a service call — or tell us exactly what to bring:
- Note whether one tap or every hot tap is affected. Do not remove electrical covers or press internal reset buttons.
- Read the display without opening the heater. Do not relight or repeatedly reset equipment that keeps shutting down.
- Tankless: read the error code off the display and write it down.
- Any heater: if you see water pooling around the base, shut off the water supply to it and call — that changes everything.
