AEGONAN Utility Heater With Built-In Thermostat
This 600W convection heater is designed specifically for freeze protection in pump houses and remote utility spaces. The unit features a built-in thermostat with a digital display and adjustable range from 40°F to 105°F, allowing automated temperature maintenance to protect pumps and piping against freezing. Its design uses X-shaped aluminum fins to increase surface area and accelerate heat transfer by convection. With no moving parts, this heater emphasizes simplicity and continuous winter operation at remote sites. The digital thermostat display shows ambient temperature by default and can present the setpoint when adjusted.
Qmark WHT500 Utility Heater
The Qmark WHT500 is a 240V, 500-watt utility heater intended for installation near pipes, pumps, or other fluid-filled equipment to mitigate freeze risk. Constructed with galvanized steel, it provides durability against environmental changes. The thermostat is enclosed in a tamper-proof control box for continuous protection and set-and-forget operation. This product is typically hardwired and aimed at permanent installations where a stable, enclosed heating solution is required to protect mechanical equipment in small utility enclosures.
YeloDeer Thermostat Outlet Plug

This temperature-controlled outlet plug offers a simple way to add thermostatic control to portable heaters or de-icers in a pump house. The unit automatically switches power on when ambient temperature falls below 38°F and off above 50°F, compatible with standard 120V devices up to 15A. Constructed from ABS and PC materials, it is marketed for outdoor and harsh cold conditions and is suitable for plug-and-play setups where a hardwired thermostat is not available. Use it with a rated heater to provide automated freeze protection without rewiring.
Garystat Heat Pump Thermostat
The Garystat non-programmable thermostat supports heat pump systems and conventional forced-air heating and includes temperature and humidity monitoring with a large LCD. It provides a stable control option for systems that use a central heat pump or furnace to maintain space temperature. Note compatibility limits: it does not support electric baseboard line-voltage systems (120–240V) or RV applications. For pump houses where central HVAC or low-voltage heating controls are used, this thermostat offers a clear interface and reliable control logic for maintaining minimum temperatures.
Yattberak Dog House Heater (IPX5)
This 500W PTC waterproof heater is designed for outdoor enclosures and pet houses and includes app-based remote control, a programmable timer, and thermostat control from 41°F to 113°F. Its IPX5 rating and anti-chew cord claim make it useful in damp or semi-exposed utility shelters where splash protection and remote setpoint control matter. The heater features automatic overheat protection and cycles to maintain set temperature. While intended for pets, its compact, weather-resistant design makes it a candidate for small pump house applications where a plug-in, controllable heater is needed.
Buying Guide: Choosing A Heater For Your Well Pump House
Protecting a well pump house from freezing requires evaluating heat output, control method, electrical configuration, durability, and safety. Below are key considerations when selecting equipment for freeze protection.

Heat Output And Sizing
- Wattage vs. Enclosure Size: Estimate cubic feet of the pump house and choose wattage that will maintain minimum temperature. Small insulated enclosures often require 250–1000 watts depending on insulation and ambient lows.
- Convection vs. Radiant: Convection heaters with fins distribute heat for overall ambient temperature control. Radiant or localized heaters warm specific surfaces (pipes, valves) more directly.
Thermostatic Control
- Built-In Thermostat: Heaters with an integrated thermostat (like the AEGONAN) simplify installation and deliver automated protection.
- External Thermostat or Outlet Control: Use a plug-in thermostat outlet (YeloDeer) for portable heaters or a hardwired control for permanent systems; ensure setpoints match freeze prevention needs (commonly 35–45°F).
- Compatibility: Confirm voltage and control type of the thermostat and heater. Line-voltage heaters need compatible line-voltage thermostats; low-voltage thermostats are for HVAC equipment.
Power And Wiring
- Voltage: Verify available supply—120V portable options vs. 240V hardwired units. Qmark is a typical hardwired 240V solution; others are plug-in 120V devices.
- Installation Requirements: Hardwired heaters may require conduit, junction boxes, or licensed electrician installation. Plug-in devices simplify install but may need weatherproof outlets in unheated enclosures.
Durability And Environmental Protection
- Enclosure Material: Galvanized steel or coated metal offers rust resistance in humid or damp pump houses.
- Water Resistance: IP ratings (e.g., IPX5) and splash protection matter if the enclosure is exposed to moisture.
- No Moving Parts: Simpler designs without fans reduce maintenance and failure points in remote locations.
Safety Features
- Overheat Protection: Automatic shutoff prevents thermal damage if airflow is restricted.
- Tamper-Proof Controls: Enclosed thermostats reduce accidental changes and improve continuous protection.
- Proper Mounting: Surface- or wall-mounted heaters should have clearance per manufacturer instructions to prevent fire hazards.
Control Integration And Monitoring
- Remote Monitoring: Wi‑enabled heaters or thermostats allow remote monitoring of setpoints and ambient temperature, useful for remote well houses.
- Simple Automation: Non-programmable thermostats provide reliable set-and-forget control; programmable or app-enabled models allow schedules and alerts.
Installation Scenarios And Use Cases
- Insulated, Enclosed Pump House: Low-wattage convection heater with built-in thermostat often suffices.
- Small Uninsulated Shed: Higher wattage or targeted pipe heating combined with a thermostatic outlet can be effective.
- Remote Sites: Choose low-maintenance designs with robust materials and remote monitoring if possible.
Comparison Perspectives
- Durability vs. Convenience: Hardwired galvanized steel units (Qmark) offer durability and continuous protection; plug-in convection units with built-in thermostats (AEGONAN) provide convenience and easier retrofitting.
- Cost of Installation vs. Flexibility: Plug-in thermostat outlets and portable heaters reduce upfront installation cost but may require weatherproofing. Hardwired solutions cost more to install but are often more secure and tamper-resistant.
- Localized Pipe Protection vs. Ambient Control: Choose radiant or direct-contact options for specific pipe protection; use convection to maintain ambient temperature for entire enclosure and equipment protection.
Note: Always follow manufacturer installation instructions and local electrical codes. When in doubt about wiring or permanent installs, consult a licensed electrician to ensure safe and code-compliant setup.
