How to Choose the Best Marine Water Heater for Your Boat

marine water heater is an important boating appliance and is responsible for heating up the water used for showering, washing-up, and other personal hygiene applications related to marine sanitation. There are several water heaters used in the boating industry, each with various functions, heating capacity, build quality, and power. This can sometimes make it difficult for buyers to find the right water heater for their maritime needs.

There are a number of factors to consider when purchasing a new water heater for your boat:

  • Strong build quality with protective features
  • Adaptability and dynamic performance
  • Size and model variation (because one size does not fit all)
  • Reliable warranty

A Closer Look at Torrid Water Heaters 

Just like your marine toilet needs a specific pump to handle your business, your boat needs a specific water heater to meet its own size requirements. Look for an established brand that carries multiple models with variation in both gallon capacity and power configurations. Torrid water heaters have been made in the United States for more than 40 years, offering 35 models for boat owners to choose from with horizontal and vertical placement options. The Torrid line offers a wide selection of capacity and voltages ranging from 6 to 80 gallons, with 12 VDC, 120 VAC, 240 VAC, and Three Phase power configurations.

Marine water heaters are exposed to high-humidity, aggressive water conditions and other harsh environmental factors, making build quality a top factor in selecting the right unit. Torrid produces high-quality and feature rich water heaters complete with glass-lined inner tank vessels to mitigate the risk of corrosion and reduce bacterial build-up. This is unique to Torrid water heaters, and compliments other enviable features such as foam-insulation, replaceable magnesium anodes, and an improved Integrated Heat Exchanger (IX) model with twice the heat transference as earlier models.

A boat’s water heater is an investment, and not one that buyers should set out to repeat year after year. To extend the life of a water heater and make the investment worthwhile, boaters should look for water heaters with stainless-steel outer jackets. Units with aluminum outer jackets aren’t as durable, and the level of protection degrades over time. Torrid water heaters come standard with 304 brushed stainless-steel outer jackets with optional powder covering to ensure the highest level of lasting performance.

Selecting the best marine water heater for your boat is an important decision, and one that requires research and understanding of the various water heater models, functions, and warranties. If you have trouble figuring out which water heater is best for you to contact us and we will help you pick the model that best suits your boating and marine sanitation needs. After all, after you use your marine toilet – you’ll need to wash up!

Fixing The 3 Most Common VacuFlush Toilet Problems

Dometic’s VacuFlush™ marine toilets are high-quality, powerful toilet systems that are only sold exclusively through distributors and dealers. VacuFlush™ toilets have a sophisticated waste disposal system that use stored vacuum vessels and diaphragm pumps to send waste to a holding tank. These marine toilets require very little water for operation, approximately one pint per flush, and are odor free. The discrete design and functionality of these marine toilets allows them to be located virtually anywhere. VacuFlush™ toilets require routine maintenance and may require the occasional tune-up. If you’re experiencing problems with your Dometic VacuFlush™ pedal-operated or electronic-operated marine toilet, there are a few simple ways to troubleshoot and get back to smooth flushin’ in no time.

General VacuFlush™ Vacuum Pump Problems

If your vacuum pump will not shut off, isolate the toilet by shutting off the water, then insert the vacuum tester into the 1” orifice of the funnel in the bottom of the toilet. If the vacuum exceeds 10” and the switch does not shut off, replace the vacuum switch. If the pump stops and the gauge reading drops, follow the line back to the inlet of the vacuum generator or vacuum tank and test the tank for any leaks. Duckbills, bellows, O-rings, and sealing grommets are all possible leak culprits. Check and replace these components periodically to avoid any unsavory surprises down the road.

VacuFlush™ Bowl Problems

Foot Pedal Operated Marine Toilets

Owners of pedal operated VacuFlush™ toilets may experience some problems involving limited water retention within the bowl. This problem is best remedied by changing the bowl seals and tightening the band clamp. If water is not entering the bowl at all, check that the mushroom cap is on the water valve stem. Make sure the screen behind 1/2” water line connection is not blocked or preventing water flow.

Electronic Operated Marine Toilets

If water is not entering the bowl, verify that water pressure is present. If so, the water valve may have failed, or the inlet screen is blocked with debris. Minimal water flow or a small trickle is indicative of a partial blockage of the water valve screen. Change the bowl seal and check to ensure that nothing is obstructing the half ball from fully closing over the seal. Water valve screens should be maintained to avoid buildup of debris.

Marine Toilet Water Leaks

FootPedal Operated ToiletsIf your Dometic VacuFlush™ toilet is leaking from the base, the floor flange seal most likely needs replacement. If the leak is coming from behind the toilet unit, check the ½” sealing grommet or vacuum breaker. If the leak starts from under the foot pedal, check the ½” water line connection or water valve.

Electronic Operated ToiletsThere are a several leak points in these toilet bowls that will need to be checked if water is not being retained. Check bowl seals, O-rings on the shaft that rotates half ball, O-ring at bottom of base, and funnel/adapter screwed to the floor. If these appear to be faulty, these parts should be replaced.
