Kodi njira zabwino kwambiri zotenthetsera nyumba yopanda gridi ndi ziti?

Pa 300% mpaka 500% + bwino, mapampu otentha ndi njira yabwino kwambiri yotenthetsera nyumba yopanda gridi. Ndalama zenizeni zimatengera kutentha kwa katundu, kutsekereza, ndi zina zambiri. Ma boilers a biomass amapereka njira yabwino yotenthetsera yokhala ndi mpweya wochepa. Kutentha kwamagetsi kokha ndiye njira yokwera mtengo kwambiri pakuwotchera popanda gridi. Mafuta ndi LPG nawonso ndi okwera mtengo komanso olemera kaboni.

Mapampu otentha

Magwero otentha ongowonjezedwanso ayenera kukhala chikhumbo chachikulu cha eni nyumba, ndipo apa ndipamene mapampu otentha amabwera ngati njira yabwino. Mapampu otentha ndi oyenerera makamaka kuzinthu zopanda gridi ku UK, ndipo akuwoneka ngati otsogola pakuwotchera kongowonjezwdwa.

Pakali pano, pali mitundu iwiri ya mapampu otentha omwe ali otchuka:

Mapampu Otentha a Air Source

Mapampu Otentha Pansi Pansi

Pampu yotenthetsera mpweya (ASHP) imagwiritsa ntchito mfundo ya firiji yopondereza mpweya kuti itenge kutentha kuchokera ku gwero limodzi ndikutulutsa kwina. Mwachidule, ASHP imatenga kutentha kuchokera kunja. Pankhani ya kutentha kwapakhomo, itha kugwiritsidwanso ntchito popanga madzi otentha (ochuluka mpaka madigiri 80 Celsius). Ngakhale kumadera ozizira kwambiri, makinawa amatha kutulutsa kutentha kofunikira kuchokera ku mpweya wozungulira wa madigiri 20.

Pampu yotenthetsera pansi (yomwe nthawi zina imatchedwa pampu ya kutentha kwa geothermal) ndi gwero linanso lotenthetsera zinthu zakunja kwa gridi. Dongosololi limatengera kutentha kuchokera pansi pa dziko lapansi, komwe kumasinthidwa kukhala mphamvu yotenthetsera ndi madzi otentha. Ndi luso lamakono lomwe limagwiritsa ntchito kutentha kwapakati kuti likhalebe lopanda mphamvu. Makinawa amatha kugwira ntchito ndi zibowo zakuya zowongoka, kapena ngalande zosaya.

Machitidwe onsewa amagwiritsa ntchito magetsi kuti agwire ntchito, koma mukhoza kuwaphatikiza ndi PV ya dzuwa ndi kusungirako batri kuti muchepetse ndalama ndi carbon.

Zabwino:

Kaya mumasankha magwero a mpweya kapena mapampu otenthetsera pansi, imatengedwa ngati imodzi mwazabwino kwambiri zotenthetsera pa gridi zomwe zimagwiritsidwa ntchito kwambiri.

Mutha kusangalala ndi mphamvu zambiri komanso kutentha kwamkati m'nyumba. Imagwiranso ntchito mwakachetechete ndipo imafuna chisamaliro chochepa. Pomaliza, simudzadandaula za poizoni wa carbon monoxide.

Zoyipa:

Choyipa chachikulu cha pampu yotentha ndikuti amafunikira kukhazikitsa gawo lamkati ndi lakunja. Ma GSHP amafunikira malo ambiri akunja. Ma ASHP amafunikira malo omveka bwino pakhoma lakunja la fan unit. Katundu amafunika malo a chipinda chaching'ono chobzala, ngakhale pali njira zogwirira ntchito ngati izi sizingatheke.

Mtengo:

Mtengo woyika ASHP umakhala pakati pa £9,000 - £15,000. Mtengo woyika GSHP uli pakati pa £12,000 - £20,000 ndi ndalama zowonjezera zogwirira ntchito pansi. Ndalama zoyendetsera ntchito ndizotsika mtengo poyerekeza ndi zosankha zina, chifukwa chakuti magetsi ochepa okha amafunikira kuti agwire ntchito.

Kuchita bwino:

Mapampu otentha (mpweya ndi gwero la pansi) ndi awiri mwa machitidwe ogwira mtima kwambiri pozungulira. Pampu yotentha imatha kupereka mphamvu mpaka 300% mpaka 500%+, chifukwa samapanga kutentha. M'malo mwake, mapampu otentha amasamutsa kutentha kwachilengedwe kuchokera mumlengalenga kapena pansi.
