Hot Water Furnaces – Installation, Repair & Maintenance

A hot water furnace is one of the most dependable heating systems for New Jersey homes. It provides consistent, radiant warmth by circulating heated water through radiators or baseboards.

Our technicians provide complete installation, repair, and maintenance for hot water furnaces — ensuring your home heats evenly and efficiently.

01

Our hot water furnace services include:

  • New system installation and setup
  • Circulator and zone valve repair or replacement
  • Expansion tank service
  • Radiator and baseboard maintenance
  • System cleaning and efficiency checks

Regular maintenance helps prevent sudden breakdowns and keeps your energy bills under control.

02

Steam Furnaces – Reliable, Efficient Heating

If your home uses a steam furnace, you already know how powerful and comforting this type of heat can be. Steam heating systems, however, require expert handling due to their complexity.

At Doctor Water Heater, we have decades of experience working with gas-powered steam furnaces. Our technicians understand every component — from pressure systems to radiators — ensuring your home stays warm and your system runs safely.

We offer:

  • Complete steam furnace installation
  • Radiator and baseboard repair or replacement
  • Steam pressure regulation and safety checks
  • Other troubleshoot and repair

We treat every system like our own — ensuring it performs efficiently and safely throughout the winter.

03

Tankless Heating Systems – On-Demand Efficiency

Looking for a modern, energy-saving heating solution? A tankless heating system could be your best investment. These systems provide instant heat without storing large volumes of water — making them highly efficient and space-saving.

Our tankless heating services include:

  • New system installation and setup
  • Troubleshooting and repair
  • Circulator and valve replacement
  • Zone valve repair and replacement on the tankless section
  • Routine performance inspections

Tankless systems are ideal for homeowners who want continuous heat with lower operating costs and less maintenance

04

Maintenance That Protects Your Investment

Regular maintenance isn’t just about avoiding breakdowns — it’s about efficiency, safety, and long-term savings.

Our annual maintenance service includes:

  • Checking circulators and zone valves
  • Inspecting expansion tanks for pressure balance
  • Cleaning radiators and baseboards
  • Inspecting gas lines and combustion efficiency
  • Testing system performance and safety controls

Preventive maintenance helps detect small issues before they become expensive repairs — keeping your system running smoothly all season long.

05

Expert Furnace Repairs & Replacements

Even the most reliable heating systems need attention over time. If your furnace isn’t performing as it should — maybe it’s taking too long to heat, making strange noises, or leaking — our experts can help.

We diagnose every issue thoroughly and provide the most cost-effective, long-term solution, whether it’s a simple repair or a full system replacement.

Common repair services include:

  • Circulator replacement
  • Zone valve repair
  • Expansion tank and pressure issue correction
  • Radiator leaks and baseboard replacement

We only recommend replacement when it’s truly necessary — and always ensure your new system is perfectly matched to your home’s heating needs.
