ADVS-W Air Source Heat Pumps
10-16 kW Single Phase Monobloc ASHP
ADVS-W is Adveco’s single phase air to water heat pump range, covering 10kW, 12kW and 16kW output for commercial sites without a three phase electrical supply. Like the rest of the Adveco ASHP line up, it runs on an R32 refrigerant circuit and sits outside the building as a single monobloc unit. On its own ADVS-W is a heat source, not a store, so it’s almost always paired with a hot water cylinder to hold the preheated water until it’s needed.

- R32 refrigerant, factory pre-charged
- Output up to 60°C, effective down to -25°C outside air

ADVS Options
ADVS10W – the entry point in the range, suited to smaller sites where single phase supply is the main constraint rather than raw output.
ADVS12W – a step up in capacity for slightly higher baseline demand, still on a standard single phase connection.
ADVS16W – the highest output single phase unit Adveco offers, for sites that need more from a heat pump than a three phase upgrade would justify.
Easy To Install & Environmentally Friendly
A complete, energy-efficient means to deliver domestic hot water all year round.
ADVS-W models provide a fully integrated monobloc heating system that can replace, or work in synergy with traditional gas or oil boilers. Available in single-phase capacity for smaller commercial specifications.
ADVS-Ws can provide domestic hot water (up to 55°C), with an exceptionally compact form factor. This enables the ADVS-W to be installed in properties where space is limited. The external installation of the unit means the available space within the plant room remains unchanged.
The ASHP is pre-charged with R-32 refrigerant at the factory, so no need for refrigerant piping making installation is quicker and easier. Compared to previous generation R410 ASHPs, ADV-W R-32 ASHPs demonstrate a reduced global warming potential (GWP) of 32% and also reduce CO₂ emissions by 75%.
The two-door design provides easy access to internal components making regular servicing and maintenance straight-forward
High-efficiency performance (A+++ ErP Energy Rating) ensures continuous hot water supply water even when at -7°C ambient air temperature. The ADVS-W range is capable of delivering output temperatures of up to 60°C even when outdoor temperatures drop as low as -25°C. The ADVS-W also monitors energy consumption data for operating cost analysis.
ADVS-W provides quiet operation, producing as little as 51 dB(A) of sound pressure, less than that of a domestic refrigerator, at a distance of just one metre.
What is ADVS-W, and how does it differ from ADV-W?
ADVS-W and ADV-W share the same monobloc design and R32 refrigerant circuit. The difference is the electrical supply each is built for. ADVS-W runs on single phase power at 10, 12 and 16kW, making it the better fit where a site doesn’t have three phase available or where a three phase upgrade isn’t worth the cost for the output needed. ADV-W covers larger three phase installations from 16kW up to 30kW. If your site already has three phase power and needs more than 16kW, our ADV-W range is worth comparing directly.
Pairing ADVS-W with a hot water cylinder
An air source heat pump on its own doesn’t store hot water, it heats it. ADVS-W is designed to run as a preheat stage into a hot water cylinder, which holds the heated water at temperature and buffers demand so the heat pump isn’t trying to chase every draw off in real time. This two part setup, heat pump plus cylinder, is the standard way commercial ASHP systems are specified, rather than expecting the heat pump to act as an instantaneous water heater on its own.
Adveco’s VB range of vented and unvented hot water cylinders is built to pair with ADVS-W and the wider ASHP line up, sized to hold enough preheated water to smooth out peak demand while the heat pump works at a steady, efficient rate.
Ideal Applications
For smaller projects, or for buildings limited to single phase capacity, ADVS-W provides all the advantages of heat pump efficiency by supplying pre-heat to low-carbon, hybrid hot water systems. These meet the stringent demands and safe DHW temperatures (+60°C) required to counter legionella in schools, colleges & universities, care homes, restaurants, hotels, offices and other commercial buildings.
