Production de chaleur — cascade modulante, COP saisonnier réel 4-7. Partie de la famille glass — comme notre BESS glass, usine à biogaz et centrale à chaleur et électricité (chaleur/électricité).
Le buffer store découple la production de chaleur de la demande de chaleur : la cascade peut se charger lorsque l'électricité est bon marché ou que le photovoltaïque est en surplus et libérer la chaleur plus tard. La stratification (chaud en haut, froid en bas) rend ce processus efficace.
Avec la masse d'eau importante de la piscine, le buffer crée la flexibilité thermique que l'IA utilise pour fonctionner avec un import réseau nul — la chaleur est pré-produite pendant les heures PV au lieu d'être réchauffée à un coût élevé.

Le scénario :La stratification s'effondre lorsque la charge et la décharge se chevauchent. Le réservoir contient toujours du volume, mais il ne conserve plus la température — le buffer cesse de tamponner sans aucune alarme.

the pool operating guideline fixes the order for refurbishments: 1) reduce losses (envelope, pool cover, insulate the surge tank, ventilation heat recovery), 2) recover heat (heat recovery, waste-water heat, filter backwash as a heat-pump source), 3) generate efficiently (heat pump > CHP > gas). This hierarchy is decisive for public grant applications: funders check whether losses were reduced before the generation investment. Concretely: insulate the surge tank, add an outdoor-pool night cover and service the ventilation heat recovery before or together with the heat-pump installation.

For pools with strongly varying heat load (outdoor heat-up in April, near-zero summer, hall pool year-round) a cascade of several modulating pool heat pumps beats one large unit. A 500 kW industrial air-water HP with inverter min 30-40 % covers a 175-500 kW window. A cascade of 4 × 125 kW pool HPs covers 37-500 kW (8 % min) via stepped switching — far closer to the actual load profile. Benefits: redundancy (loss of one HP is 25 % of capacity, not 100 %), better modulation onto the PV profile, less cycling in low summer load.
Basis: the heat-pump performance guideline / the pool operating guideline
Modern inverter pool air-to-water heat pumps reach rated-point COPs (source 26 °C, sink 27 °C) between 14 and 18 (e.g. AquaForte InverterPro 16.5, Microwell HP1500 Split 17, Pontaqua Inverter+ 14). These are data-sheet values at the thermodynamically most favourable operating point. The seasonal COP (SCOP) — accounting for heat-up phases, cooler sources and standstill losses — sits at 8-12. Inverter pool HPs typically modulate between 30 % and 100 % of rated output; some industrial models (Carrier 30RB, Stiebel WPL) down to 25 %. The source must be > 5 °C for the evaporator to work without icing.

The applicable standard defines the seasonal coefficient of performance (SCOP) averaged across the year. Crucially it includes heat-up phases, standstill losses and auxiliary loads (pumps, controls). A realistic SCOP for an inverter pool air-water HP on a warm source is 8-12 (versus a rated-point COP of 14-18). Factors that depress SCOP: a cold source in winter (outdoor air), a high sink (pool heat-up) and frequent cycling (oversizing). For grant applications a conservative SCOP of 8 is advisable — even where a model computes 11.3, that is a best-case assumption.

Filter backwash water is the most valuable heat source for pool heat pumps. Temperature: pool set-point minus 3-5 K (26 °C for a hall pool, 19 °C outdoor). Volume: typically 1× the filter-bed volume per day, approx. 5-10 m³ per filter. Energy content: with a 60 m² backwash tank surface at 25 °C water this yields 290 kWh/d of usable heat on the HP evaporator side. Connection: a heat exchanger between backwash water and the HP brine loop keeps the evaporator clean. Investment: ~10 k€ for the exchanger + controls.
