Pentair MasterTemp 400 is made of cupronickel or copper & nickel alloy. This makes the product durable, more than what standard copper offers. Nickel makes the alloy more resistant to corrosion and stronger. Copper ensures the alloy does not lose its ductility. This type of allow is used in many marine applications. They can withstand exposure to seawater or saltwater. Freshwater, chlorinated water and saltwater cause different types of corrosion in metals and alloys as well as in modified resins or plastics. The heavy duty model is even better in this regard but it is pricier.

Pentair MasterTemp 400 is a relatively lightweight heater. Those who have a saltwater system should choose the heavy duty variant, otherwise the standard model is fine. The pool heater has several buttons with different functionalities. The pool on button provides temperature control. The spa on button does the same but for a spa.

The stack flue sensor provides further protection against overheating. The heater can be installed on surfaces that are known to be combustible.

Price

The first thing that ought to be mentioned in our Pentair MasterTemp 400 review is its price. The model is certainly not among the most inexpensive heating systems you can get for a pool, whether saltwater or otherwise. The heavy-duty variant is costlier and the most premium variant for this model costs even more. Many customers might feel the need to go for the heavy duty model straightaway. The materials are more durable. No one invests or wants to consider a new pool heater every now and then. It is a long term investment that is expected to pay off over many years. Pentair is known for such durable models and all three variants of the MasterTemp are worthwhile but the heavy duty is better than the standard.

The type of pool one has, its size and the water system will determine or at least influence the choice of heater. The heater should be installed properly to function optimally. Those who are not familiar with installation of pool heaters should not attempt to do it themselves. Getting a professional installer is the safest option. MasterTemp performs best when the water chemistry is proper. The lifespan of the heater and pump as well as the filter can be prolonged if the pool water is maintained properly. Pentair 460736 MasterTemp 400 is efficient, fast and durable. The heavy duty variant is more effective and requires fewer servicing sessions down the line.

Pentair has a pool volume calculator. Pool owners should use this to find out which model is appropriate for their prized installation. This can do away with the need for guesswork. Do not just go by the size of the pool. Calculate the volume of water. The package comes with all important documents, including manual and installation guide, a brochure, an installation checklist, the bypass access plug kit an dimensions diagram. Customers should be aware of water chemistry to extract the best performance over the longest period of time from any of the three MasterTemp 400 models.

Pros and Cons of Pentair MasterTemp 400

The pool heater is efficient and effective. It is not among the largest or the heaviest pool heaters. The three variants provide enough options.

Pool owners who understand the water and are familiar with such equipments will not have a hard time dealing with the product or maintaining it to last a decade and longer. If there is a con, then it might be the price for some. Pentair MasterTemp 400 is somewhat expensive but that is unavoidable when you want to buy a premium product.

Pricing of Pentair MasterTemp 400

Customer Reviews of Pentair MasterTemp 400

Most customers are happy with the Pentair MasterTemp 400. With the few exceptions where customers have had issues with sellers in particular and packaging, customers have been generally content with the whole process of buying, installing and using the product. Some customers are unhappy with the performance but most such cases have been due to water chemistry and misplaced expectations. Pentair has clearly stated in its manual and elsewhere that the water system or how acidic the water is will influence the functioning of the heater. The heat exchanger will get damaged in acidic water. Customers who ignore this are not too satisfied.

A typical Pentair MasterTemp 400 review from customers is that it can work really fast but some have highlighted the need for a separate power source for the control panel. The heater can raise the temperature of a fifteen thousand gallon pool by as much as three degrees in sixty minutes. This is considerably commendable performance. Smaller pools can be heated up much faster. The external or ambient temperature also plays a role here.

Conclusion

Buy the Pentair MasterTemp 400 if you want a quality pool heater. Go for the heavy duty variant if you want impeccable performance, better durability and less dependence on servicing or maintenance.
