Mae rhai profiadau diweddar - yn bersonol ac yn broffesiynol - wedi gwneud i mi feddwl am sut mae uchelgeisiau a chynlluniau (waeth pa mor fawr a chyffrous) yn tueddu i ddibynnu, ar ddiwedd y dydd, ar bethau cnau a bolltau eithaf sylfaenol. Cymerwch adeiladau ynni effeithlon fel enghraifft. Mae'n hawdd cyffroi am ddyluniadau pensaern\u00efol, nodweddion ffansi, a hyd yn oed rhestr drawiadol o rinweddau amgylcheddol eiddo. Rydyn ni i gyd yn hoffi Grand Designs. Ond y gwir amdani yw bod llwyddiant yr adeiladau hyn yn dibynnu'n gyfan gwbl ar ddibynadwyedd ac effeithiolrwydd rhai peiriannau eithaf di-glamorous (MVHR neu bwmp gwres) a rhai tasgau digon annifyr (ee selio tyllau gyda th\u00e2p).<\/p>\n\n\n\n
Dyna pam ei bod mor bwysig bod prosesau fel gosod a chomisiynu unedau (pympiau gwres a MVHR) a gwiriadau aerglosrwydd yn cael eu gwneud yn gywir a hefyd pam mae cyfathrebu da rhwng gwahanol bobl sy'n gweithio ar brosiect yn bwysig.<\/p>\n\n\n\n
Beth all fynd o'i le gyda gosod MVHR a Pwmp Gwres?<\/em><\/p>\n\n\n\n An MVHR unit may not be installed correctly\u2014bad duct design, or incorrect duct types (“flexi” duct is often used, even though industry guidance is to use a maximum of 1.3m of flexi ducts on MVHR installations. Personally, we never use any of flexi duct)\u2014or it may be badly commissioned and incorrectly balanced. Bad design and installation choices can mean that airflow may not reach all the areas it should (leading to damp or condensation or varying levels of CO2 through the house). A system wrongly installed is also likely to need more maintenance, with more wear on fans and other system components: an unnecessary expense that also gives the systems a bad name.<\/p>\n\n\n\n Similarly, heat pumps need to be properly installed if they are going to be produce the optimal coeffecient of performance (4 or 5). If a heat pump is oversized for the property this can lead to a decrease in coefficient of performance (sadly, average coefficient of performance for buildings in UK is in the mid 2s). Knowledge of good design for low flow temperatures is really critical. Heat Geek is at the forefront of pushing out really good information and training but these have not yet reached the wider installer community.<\/p>\n\n\n\n Yr anhawster i berchennog t\u0177 yw sut i wybod at bwy i fynd. . . Sut ydych chi'n gwybod y bydd angen i osodwr wybod beth sydd angen iddynt ei wybod? Dyma ychydig o awgrymiadau: Ac ar gyfer pympiau gwres, gwiriwch gyda'r gosodwr ar rai cwestiynau allweddol: Some recent experiences\u2014personally and professionally\u2014have got me thinking about how ambitions and plans (no matter how big and exciting) tend to rely, at the end of the day, on some pretty basic nuts-and-bolts stuff. Take energy efficient buildings as an example. It is easy to get excited about architectural designs, fancy features, and even an […]<\/p>\n","protected":false},"author":2,"featured_media":173,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"nf_dc_page":"","footnotes":""},"categories":[9,8],"tags":[],"class_list":["post-169","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-passivhaus","category-ventilation"],"_links":{"self":[{"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/posts\/169","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/comments?post=169"}],"version-history":[{"count":3,"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/posts\/169\/revisions"}],"predecessor-version":[{"id":172,"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/posts\/169\/revisions\/172"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/media\/173"}],"wp:attachment":[{"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/media?parent=169"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/categories?post=169"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/adeiladu.cymru\/cy\/wp-json\/wp\/v2\/tags?post=169"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
Ar gyfer awyru, gwiriwch a yw'r gosodwr wedi'i achredu gan BPEC (BPEC) https:\/\/bpec.org.uk
Check if the installer has a record of good installations they have done.
Ar gyfer pympiau gwres, edrychwch ar Heat Geek am fap o osodwyr. https:\/\/www.heatgeek.com\/find-a-heat-geek\/
