Garage, Workshop & Cabin Heating

Specialized Heating for Your Garages, Workshops and Seasonal Cabins

Heat Built for the Spaces You Actually Spend Your Time In

Last winter, a Gilford car collector told us his garage heater kept a prized vintage Mustang running while neighbors were dealing with frozen fuel lines. That is the difference the right unit makes in a space a standard furnace was never meant to reach.

Whether you are holding a classic car collection at a safe temperature in Gilford or adding heat to a historic Weirs Beach cottage, our technicians have the training and the code knowledge to do it right.

The Modine Hot Dawg: The Best Choice for Your Workshop

A cold garage in a New Hampshire winter is more than uncomfortable — it puts your home’s pipes and your vehicles at risk. We are a top installer of the Modine Hot Dawg series, the most popular gas-fired unit heater for homes in North America.

For workshops with wood dust or paint fumes, we recommend the Separated Combustion model. These units pull all their air from outside, so indoor dust never reaches the burner. That makes the heater safer and helps it last longer.

No natural gas or propane at the building? We also offer electric and alternative-fuel heaters, and our team will help you pick the right unit for whatever energy source you have.

Why Homeowners Pick the Hot Dawg
  • Six sizes — from a one-car shed to a large multi-bay garage
  • Saves space — slim enough to mount just one inch from the ceiling
  • 80% efficient — an average two-car garage burning 400 gallons of propane a season could save up to 80 gallons over the winter
  • Flexible venting options for almost any building layout
  • Quiet fan — a real difference if you spend hours in the shop

Direct Vent Wall Furnaces Where Ductwork Is Impossible

Many beautiful homes from Meredith to Center Harbor have architecture that simply will not accept ductwork. For those spaces, we use direct vent wall furnaces — you may know them as Monitor or Toyotomi-style units.

  • No chimney needed — a small pipe through an exterior wall pulls fresh air in and pushes exhaust out
  • Up to 93% efficient, with models that install as a fireplace insert for looks
  • Safe indoor air — sealed systems never burn the oxygen in your house, so the air never feels stuffy
  • Steady heat — the flame adjusts automatically instead of cycling on and off

Not Sure How Much Extra Heat Your Space Needs?

If your main heater cannot reach the far corners of the house during a ten-below cold snap, a wall heater is a cost-effective fix. Ask us for a free sizing check before the next cold snap — available throughout Belknap County and the neighboring Lakes Region towns, with no hard sell.

We Do More Than Hang a Heater on the Wall

Installing these units takes a real understanding of local codes and safety standards. We leave enough clearance around the unit so it stays safe and is easy to service later, and we pressure-test all gas piping for leaks. We can even tie your new heater to a wireless thermostat so you can warm the shop from your phone before you head out.

We are upfront about cost, too. Most Modine Hot Dawg installations start around $2,200, including equipment and labor, and direct-vent wall furnaces generally run $2,800 to $4,500 depending on size and features. Building size, fuel source, and options like thermostat upgrades move the number, so we give you a clear quote before we begin — no hidden fees.

Your Annual Tune-Up Includes

Garage heaters live in dusty places. Skip the yearly service, and they can become a fire hazard.

  • Cleaning burner assemblies and the heat exchanger
  • Inspecting and testing all safety shut-offs
  • Checking for gas leaks
  • Examining wiring and controls
  • Inspecting the venting system for blockages
  • Replacing the air filter, if applicable
frequently asked questions

Specialized Heating Questions From Lakes Region Homeowners

What size heater do I need for my two-car garage in Laconia?

For a standard, insulated two-car garage, a 45,000 BTU Modine Hot Dawg usually works well. If the space has high ceilings or no insulation, we may suggest a larger unit, such as a 60,000 or 75,000 BTU model.

Is it safe to run a gas heater in a woodshop?

Yes, as long as you use a model like the Modine Hot Dawg HDS. These units pull fresh air from outside, so wood dust and paint fumes never reach the open flame.

Can I install a wall furnace in a room without a chimney?

Yes. Direct vent furnaces are designed to vent through any exterior wall. They need no chimney, just a small pipe that can be hidden behind the heater.

How much space does a Modine Hot Dawg take up?

These units have a low-profile design and mount very close to the ceiling on just two brackets, which keeps your floor and workspace completely clear.

Do these units help with humidity in a lakeside cabin?

Heating the air naturally lowers relative humidity. For tighter control, we can talk about adding a dehumidifier to keep the cabin dry and mold-free through the summer as well.

How often should I have my garage heater checked?

We suggest an annual tune-up every fall. It matters even more for garage heaters, because dust from your projects accumulates on the burner and can create a safety risk.
