Your statement that there's only 1 CENTON seller is not true , as I saw multiple sellers selling similar models. Most brands on Shopee, if not all, will have multiple sellers, unless it is an exclusive distribution privilege.

Hence I mentioned its a 'quick scan' rather than a 'detailed report', picking what might looks like the best seller for each brands as comparison. Yes I agree with u that this quick comparison is neglecting smaller sellers, so if u have the time to consolidate the data to provide a more detailed findings, feel free to share your findings here for the benefit of the rest in this thread.

CENTON Forza is a multipoint instant water heater, so yes it will turn off automatically when there's no water flowing thru it.

And since it is a multipoint, so yes u can use similar piping arrangement as per your storage water heater, as long as the current one is compliant and can sustain hot water temperature, not forgetting the discharge piping for the pressure relief valve.


The upsides are:
1. the size is small and compact; as opposed to a much larger sized storage water heater.
2. literally no waiting time (only few seconds before getting hot water); as opposed to a storage water heater where u have to wait about 15 to 30 minutes if the water in the tank is completely unheated (the larger the tank capacity, the longer the waiting time).

The downsides are:
1. Much lower output water temperature, at max only 50°C (the higher the water flow, the lower the output water temperature); as opposed to a storage water heater which is 75°C at max output.
2. Much higher electrical wirings and components requirements since its power rating is high (if I'm not mistaken there are 5.5kW and 7.0kW option); as opposed to a storage water heater which is usually not more than 3.0kW, hence required much lower-spec wirings and components.


If you want to replace your old storage water heater and u do not have a space constrain, I suggest u to stick with a new storage water heater to get similar output water temperature / shower experience, as changing to a CENTON Forza multipoint instant water heater will give u a lower output water temperature, and requires u to upgrade your electrical wirings and components (which can be a headache as it might involves wall and ceiling hacking as well).

External booster pumps, especially powerful ones like Grundfos, are usually paired with storage water heaters like CENTON Neptune, or if u prefer instant water heaters, the multi-point ones like CENTON Forza (that comes with copper tank, with power rating of 5.5kW or 7.0kW).


CENTON Serene Highlands 5.4kW is a single-point instant water heater, and here's a few reasons that instant water heater might not be sufficient:

1. High Water Flow | Your water flow will be very high with Grundfos pump, hence 5.4kW power rated instant water heater might barely give u a lukewarm output water temperature (the higher the water flow, the lower the output water temperature). U might need a 7.0kW like CENTON Forza (if your electrical wiring and component spec is sufficient to support such high power rating) to sufficiently heat up the water before reaching you. A storage water heater like CENTON Neptune will definitely be sufficient, hence is the best choice.

2. High Water Pressure | That model is a single-point model (comes with a plastic tank), which can withstand up to 55psi water pressure only. You Grundfos pump might output water pressure that exceed that, which will damage the water heater's plastic tank in a long run. Hence, if u insist of using instant water heater, a multi-point model like CENTON Forza is safer (can withstand up to 87psi), or best option, to go for storage water heaters like CENTON Neptune (can withstand up to 116psi).

3. Shower Accessories Compatibility | U have to use the shower accessories that comes with that single-point model (else your warranty will be voided). Hence if u want to use your own sets of shower accessories (eg. those that built-into your bathroom walls), go for multi-point models like CENTON Forza is safer (free to use with any shower accessories), or best option, to go for storage water heaters like CENTON Neptune.
