When you're shopping for heating-system accessories, the options rarely compete on the same feature set. You might need to restore a heat pump's control board, give an outdoor condenser a stable base, or add a continuous hot-water supply to a commercial counter. This breakdown puts four options next to each other: a replacement control board, two equipment pads, and an auto-refill water boiler, with listed prices from $46.99 to $200.95.
Quick take
If your heat pump is throwing sensor faults or the display is blank, the Auto Heat Pump Control Board is the direct replacement. For outdoor equipment that needs a wide base, the Equipment Pad is the larger choice with 300-pound support. The Mini Split Pad is a lighter option built for ductless systems, and the Commercial Hot Water Dispenser handles continuous hot water for cafes, offices, tea shops, and restaurants.
Listed price comparison
| Product | Listed price | Price bar |
|---|---|---|
| Auto Heat Pump Control Board Display for Pentair UltraTemp | USD 189.99 | |

Decision matrix
- Choose the Auto Heat Pump Control Board Display when your setup is a Pentair UltraTemp or ThermaFlo heat pump and the current board is showing unreadable messages or repeated sensor codes.
- Choose the Equipment Pad when you need a roughly 36-inch square outdoor base for a condenser unit, heat pump, or pool pump.
- Choose the Mini Split Pad when you own a ductless mini-split in the 9,000 to 36,000 BTU range and want a gray pad that stays light.
- Choose the Commercial Hot Water Dispenser when you want a plumbed-in, auto-refill water boiler rather than a countertop kettle.
Product notes
Auto Heat Pump Control Board Display for Pentair UltraTemp
This board is built as a direct replacement for UltraTemp and ThermaFlo heat pumps, aiming to restore full automation and precise temperature control when membrane buttons stop responding, the LED display is blank or corrupted, or sensor fault codes keep the compressor from cycling. The kit includes the exterior ABS bezel and interface membrane overlay, and its 90,000-140,000 BTUh rating helps it match common pool and spa systems. A United States origin is also worth noting. The limitation is fit: it is specific to the Pentair-style control board platform, so it only makes sense if your current system matches that family.
Equipment Pad for Air Conditioner Heat Pump Systems
This pad is the broadest option here, with a 36-by-36-inch footprint and a 2-inch thickness for an outdoor condenser, heat pump, or pool pump. The molded polypropylene construction is rated for a working temperature range of -48°F to 180°F, and the 12.97-pound listed weight gives it a solid feel. Support is listed at 300 pounds, which is lower than the Mini Split Pad's rating even though this pad is larger in area. If your equipment is heavy but fits within a 36-inch square, this is the pad to measure against.
Mini Split Pad for Ductless Air Conditioner Heat Pump Systems
Designed for ductless air conditioners and heat pump systems, this pad measures 37.8 inches wide, 11 inches deep, and 2.91 inches high, and it weighs 7.9 pounds. It is noticeably lighter than the Equipment Pad, and its listed 400-pound capacity is higher than the larger pad's rating. The gray pad works in residential or light commercial applications and is intended for systems from 9,000 to 36,000 BTU. The main limitation is the narrow 11-inch depth: a wide or tall condenser might overhang, so compare your unit's footprint before committing.
Commercial Hot Water Dispenser
This dispenser connects to a water supply through a 1/4-inch quick-connect inlet and refills itself as you draw hot water, removing the need for manual filling. The 8.45-quart (8-liter) tank uses a 1,500-watt heating element and delivers a flow rate of 12 gallons (45 liters) per hour, making it a practical station for busy cafes, offices, tea shops, and restaurants. It can provide a first cup of boiling water in about 10 minutes from a cold start, with step-heating designed to keep cold water from mixing with the boiling water. The 304 stainless steel and copper faucet fit the commercial look. It requires a plumbed water line, so it is not a drop-in portable countertop unit.
Final recommendation by use case
- For a heat pump with a failing display or sensor errors: choose the Auto Heat Pump Control Board Display.
- For a larger outdoor unit that needs a wide base: choose the Equipment Pad.
- For a compact ductless mini-split where light weight and strong load capacity matter: choose the Mini Split Pad.
- For continuous hot water at a service counter: choose the Commercial Hot Water Dispenser.
